Thank you so much. My chemistry professor had screwed me up and made it more complicated than it was supposed to be. You made it much simpler so thank you!
thank you for helping out younger generations! sometimes our own professors make it difficult that it is! Currently in General Chem 1 and you have helped out so many of my classmates!
hello, i wanted to thank you for all the videos you've skillfully made and posted. I'm studying biology with the open university in the uk and your videos are really helping me to get round concepts which are otherwise difficult to grasp from the existing litterature. I listen to your videos in the car whilst going to work ( not watching of course unless at a red light) and the recording quality is good so that despite the noise of traffic i can clearly hear everything , so many thanks for this high quality and impressive biology lessons database !
Thank you so much! I wasn't understanding this concept in class, and found this video at home. After watching it, I now understand the concept I was not understanding without hiring a tutor and saving my grade. Again, thanks for the well developed and helpful video!
As a fellow chemistry teacher, I appreciate using your videos as additional resources. They are great! However, there are two errors in this video. The net ionic equation should show only 1 mole of lead II iodide (should not have a coefficient of 2 in the equation). Also, the descriptor for the ppt is incorrect and should be listed as (s) and not (aq). Love your videos :)
Noticed the same, I learned this concept yesterday and watched a video by ChemistNATE which really solidified my understanding. This video seemed rushed in comparison and didn't do as well of a job of explaining the process he went through. I would highly recommend referring your students to that video instead.
Thankyou so much saved my life you explain it so well. I got a chem benchmark mark so i figured that i should figure it out rather than guess from what me teacher taught
Thank you thank you thank you!! My teacher has been absent, and so we didn't really learn this that well, and we still have the exam tomorrow. But you helped, so thank you!!!!!
When Iodide is mixed with the following cations the solubility is low which results in a precipitate to be formed. Ag+, Pb^2+,Hg2^2, Cu+, Ti+. All other elements that form a compound with Iodide will dissolve. Hope that helped! For future questions you can search for a table that shows you the rules. " Solubility Rules for Ionic Compounds in Water"
On your net ionic equation, where you have Pb + 2I --> 2PbI2 shouldn't it say (s) after the product instead of (aq) since we were talking about a precipitate?
For your Net Ionic Equation, shouldn't you Lead Iodide say (s) for solid instead of (aq) because it's the precipitate? Also so do you have to balance your reaction in the molecular equation and then again in the net ionic equation? Edit: Forget that last question, in the net ionic equation, the 2 next to the Lead Iodide is just a typo right? (It's already balanced without it).
I am pretty sure there are two mistakes for the net ionic equation: 1. Pb2+ + 2I- --> 2PbI2 does not make sense, it is not balance. Should it be: Pb2+ + 2I- --> PbI2 2. Since PbI2 is a precipitate, it should be PbI2(s). Every equation except for the net ionic equation write that correctly, but the net ionic equation writes it as PbI2(aq). I am not trying to be a jerk about this, but I just wanted to let you know. If I am mistaken, could you please explain why? Thank you.
Hello Sir, what type of Ionic reaction would this be: Na2CO3 + 2H[+] ----> 2Na[+] + CO2 + H2O I'm not sure if I balanced that right. Also, what is the state (l, s, g, aq) of each compound? Na2CO3 (?) + 2H[+] (?) ----> 2Na[+] (?) + CO2 (?) + H2O (?) Thank you.
Thank you so much for the life-saving video. But I am still uncertain how you know that PbI2 is a solid, not KNO3. By that, I mean how do you know that KNO3 are spectators ions to cancel out?
I don't understand how the lead iodine became aqueous in the net ionic equation, also how is that equation balanced? To me it's saying that there's 4 iodine in the product compared to 2 in the reactant, along with 2 lead compared to 2
i always end up watching this guy for one reason or another...strangely, over a wide variety of subjects...how does he know so much useful stuff? Hmm...I will stay in school...
Milo Barrera Why is Pb2+2l -> 2Pbl2? Since 1Pb on the left and should it be 1Pb on the right? But it showed 1Pb on left and 2Pb on right now. Kindly please teach me. Thank you.
Why didn't you write lead nitrate as "lead (II) nitrate"? This was really helpful, don't get me wrong, but I just got confused there and I went searching for nomenclature videos to help me understand how to write formulas.
Chemistry is so annoying, especially in college. Thanks for teaching me more than my first 2 months of the semester.
Same situation here
I'm learning this in 10th grade and also good job graduating

You have literately been teaching me chemistry this entire year. Thank you!
It's been 7 years how are you and your Chemistry
Thank you so much. My chemistry professor had screwed me up and made it more complicated than it was supposed to be. You made it much simpler so thank you!
Does anyone else have chemistry test tomorrow? :))
i hate it today. i should have studied. i have no idea what im doing.

thank you for helping out younger generations! sometimes our own professors make it difficult that it is! Currently in General Chem 1 and you have helped out so many of my classmates!
8:06 there should be Pb2+(aq) + 2I-(aq) ---> PbI2(s). Two mistakes, I hope this helpful.
Wrong
@@pullingthestrings5233 go study chemistry, kid. Or prove me that I am wrong.
@@justAliked hope do you get a subscrit when you're supposed to list the charge
Nates right, I was confused when he changed the state of PbI2
Dude you Rock !!!!!! Thanks man , i have exams next week and you've totally just taught me that in 10 mins when my teacher is taking two months

Excellent video...but i think you made a mistake with your net ionic equation around 7:54 when you wrote that PbI2 was aqueous ......

Bless you, i was about to start crying from confusion LOL
you as well as tyler dewitt have saved me from chemistry
hi,
first and for most, thank you for all your videos, they are very helpful. i have a question. how do we know on 5:40 that PBI2 is a solid?
I will forever be grateful for your videos.
Thankyou so much saved my life you explain it so well. I got a chem benchmark mark so i figured that i should figure it out rather than guess from what me teacher taught
I have a quiz in 30 minutes and I just learned this, thanks my guy
Thank you thank you thank you!! My teacher has been absent, and so we didn't really learn this that well, and we still have the exam tomorrow. But you helped, so thank you!!!!!
Thank you! This helped a lot! I was confused by this in class, but watching your video really helped!
Thank you for teaching me what my teacher could not
thank you thank you so much!! I didn't catch it during class and I got it here! and I have watched your videos before too, so yes THANK YOU!
Thanks for this, it really helped refresh me for my chem final!
should end with Pb2+ + 2I- = PbI2
This is literally the greatest and most blatant video ever
Thank you! I have a chem test tomorrow and this helped a lot :) very easy to follow
Well, how did you do?
Thank you for making this make sense, I know it’s a 10 year old video but ya girl be ✨struggle bussing✨ in my Chem 101 class
You are a God among teachers! I love you!
How do you magically get 2PbI2 from 1Pb and 2I? Also, how do remove spectator ions with different coefficients?
At 6:30 how would you know that the PbI2 is a precipitate
Solubility rules
DEP Networks precipitate is insoluble
at 8:02 the Pbl went front being a solid to being an aq. That was just a mistake, right?
OMG. I swear, I had a question ready to give to my question tomorrow morning, and then I saw this video. How coincidental is that! Haha great vid!
at 7:54, the 2PbI2 should be solid, not aqueous, right?
Brocaserter Ii yeH
You always help clarify things for me!! Thank you!
Thank you so much! I am in Chem 111 and this video helped out a lot!!!
@Bozeman Science 8:05, you wrote Pbl2 (aq) while it should be an (S)
I love you bozeman
why is the 2Pbl2 at the end of the video an aqueous?
it should be solid, he made a mistake
He made 2 mistakes..
Thank you! Really wish you taught at my college... these professors cannot teach.
Shouldn't the net ionic be Pbl(subscript 2) not 2Pbl(subscript 2). Not sure where the 2 coefficient comes from. Thanks! :)
Excellent work... clearly expalined
omg this saved me for my midterm tomorrow!!!
I believe there was a mistake on min 8:06; PbI2 (aq) should actually be PbI2 (s).
Awesome Video! It really helped me. Thanks :)
how do you get the charges for the ionic equations?
When Iodide is mixed with the following cations the solubility is low which results in a precipitate to be formed. Ag+, Pb^2+,Hg2^2, Cu+, Ti+. All other elements that form a compound with Iodide will dissolve. Hope that helped! For future questions you can search for a table that shows you the rules.

On your net ionic equation, where you have Pb + 2I --> 2PbI2 shouldn't it say (s) after the product instead of (aq) since we were talking about a precipitate?
It should read PbI2 (s) I think.
Frantisek Plasil should be a careless mistake, good to point out though
LOVE your videos, best
AWESOME!!! Perfect MCAT Review!!! :)
Nyc one ma guy......you ve just made an A for me.keep it high.
For your Net Ionic Equation, shouldn't you Lead Iodide say (s) for solid instead of (aq) because it's the precipitate? Also so do you have to balance your reaction in the molecular equation and then again in the net ionic equation?
Edit: Forget that last question, in the net ionic equation, the 2 next to the Lead Iodide is just a typo right? (It's already balanced without it).
Great video as always! Pretty sure the pbI2 is solid and not aqueous though at the end there in the NIE though!
And also it should be PbI2 not 2PbI2 right? But over all it was so help full
how do you know when it is aq or solid. In my class we used some kind of table to predict it.
Why does 2PbI2 go from being solid in the ionic equation to being aqueous in the net ionic equation?
great video to watch when you get high and forget about a quiz tomorrow :)
Very helpful video. I have a much better grasp of this now.
I am curious about the balancing of the net ionic equation at 8 minutes. I am unsure how that is balanced. Thanks!
Thank you this video helped me a lot!
did you make a mistake at 8:06 with 2PbI_2....shouldn't it just be 2PbI
i love this channel! you sir are amazing!
Thanks. U help me a lot with grade 8 chemistry problem
great teacher !!! thanks a lot keep up the good work!!!! Thank YOU VERY MUCH!
I am pretty sure there are two mistakes for the net ionic equation:
1.
Pb2+ + 2I- --> 2PbI2 does not make sense, it is not balance. Should it be:
Pb2+ + 2I- --> PbI2
2.
Since PbI2 is a precipitate, it should be PbI2(s). Every equation except for the net ionic equation write that correctly, but the net ionic equation writes it as PbI2(aq).
I am not trying to be a jerk about this, but I just wanted to let you know. If I am mistaken, could you please explain why? Thank you.
Eddie Ed same here can someone clarify
same someone should answer this
I actually understand. thank you. now I a chance of actually passing my test Tmr.
why is PbI2 solid in ionic equation and not solid in the net ionic equation?
thank you so much for uploading this video it helped me alot!!!
Yes i can finally say I truly understand without hesitating
Hello Sir,
what type of Ionic reaction would this be:
Na2CO3 + 2H[+] ----> 2Na[+] + CO2 + H2O
I'm not sure if I balanced that right.
Also, what is the state (l, s, g, aq) of each compound?
Na2CO3 (?) + 2H[+] (?) ----> 2Na[+] (?) + CO2 (?) + H2O (?)
Thank you.
great video, helped a lot.
Forgot how to do net ionic
Thanks~ Swept my worries right into the trash
Why is lead iodide solid - isn't it an ionic compound? Shouldn't it dissolve to for a solution?
Helpful and simple
You are my chemistry teacher.
it was very very helpful !
ah! Thank you so much! :) Makes so much more sense now.
How do you know if the ions are going to break apart?
this is very helpful, thank you very much
Very helpful! Thank you!!
does anyone know when he does ionic equation he just keeps PbI2 (do not break into Pb^+2 and I2 ), does anyone know why? please Help me out TT^TT
All solids don't seperate
that was very helpful. Thank you!!!
Thank you so much for the life-saving video. But I am still uncertain how you know that PbI2 is a solid, not KNO3. By that, I mean how do you know that KNO3 are spectators ions to cancel out?
Thank you!!! That's very help full
So helpful, thank you so much!!😁
I think there is a mistake at the final answer of the ionic equation.
Wooow. I get it now! Thank you so much!
Very helpful! Thank you :)
Thnks,very helpful for my homework
HOW DO YOU KNOW WHERE THE SUBSCRIPTS GO IN THE EQUATION I NEED HELP
Like solid (s) and (aq)?
(s) and (aq) solubility rules
what about for gases
Cu carbonate and hcl plz tell how to make ionic equation
KRL AGORA TUDO FAZ SENTIDO. MUITO OBRIGADA!!!!
I don't understand how the lead iodine became aqueous in the net ionic equation, also how is that equation balanced? To me it's saying that there's 4 iodine in the product compared to 2 in the reactant, along with 2 lead compared to 2
+Damian Quiroz I don't understand this either .-.
+Damian Quiroz he messed up. There isn't supposed to be a 2 in front of PbI2(s). It's supposed to be Pb + 2 I = PbI2
Very helpful!
Thanks for the help!
This is very helpful!!
Love your profile pic!!
Haha! Thanks!
i always end up watching this guy for one reason or another...strangely, over a wide variety of subjects...how does he know so much useful stuff? Hmm...I will stay in school...
why do you get 2 PbI2 rather than just PbI2?
Ahhhhh duh . Thank you :) Milo
Milo Barrera Why is Pb2+2l -> 2Pbl2? Since 1Pb on the left and should it be 1Pb on the right? But it showed 1Pb on left and 2Pb on right now. Kindly please teach me. Thank you.
Thank you sir 💖
Why didn't you write lead nitrate as "lead (II) nitrate"? This was really helpful, don't get me wrong, but I just got confused there and I went searching for nomenclature videos to help me understand how to write formulas.
Hi Mr Andersen.
Is it just me or is precipitate spelled wrong?
Thank u so much 😊
