It's almost 1 am I have my chemistry final exam tomorrow and I've been watching your videos all the afternoon and I have learned more with 5 MINUTE VIDEOS than with MONTHS of chemistry classes. Thank you so much and keep going cause I'm starving for new ones hahahaha
Man, I want to hug you or kiss your hands.You have cleared my doubts of 3 months in 8 minutes. Our teachers only deal with quation and formula , they don't explain pre -state or condition with this solution.Thanks man.As a citizen of developing country, we, students, always are out of modern laboratory and experiment, Kind people like you are giving free highly valued education.I don't want to disrespect your efforts by saying " Thank You ". May Allah bless you.
I really respect your style of covering the topic in a simple way . I suggest making a quiz about the topic in the description box . this will be helpful
Hey Proof. Dave ... Haven't forgotten about my promised donation to you for your help with orgo chem in general. It's been a few months. There has been a major delay in my tax returns. The beloved IRS. Anyway will be sending you something soon. It was to be in March but that wasn't the case. I continue to be a huge fan of the science you bring to Life via you tube !
woah! had to restart this video cause I couldn't get over how good prof looks with this haircut😅but thank you for the videos - they're always so helpful.
Hi Sir, Your video is so Good Easy too understand and so much of colour text makes interest for learners, I love your every single videos Thanks a lot for making this all videos
Good job, I go to your channel to get a general idea of the concept before I try to learn how to do the multitude of different versions of the chemistry questions. Thank you again.
I have two questions: 1.For your first example problem (6:00) when you broke down CuBr into Cu and Br you didnt put a subscript of 2 on Br. isn't Br diatomic? 2.In the Ksp formula do subscripts count as coefficents and go above the element? Or in the ICE table do you count them as a coefficent?
Molecular bromine is diatomic. CuBr is an ionic compound consisting of one ion of each element. Coefficients that apply to each ion become exponents in the formula.
Hello i am twelve years old and I am admired by your lessons and solubility too, so I subscribe u!!! And I love some chemistry college lessons and organic chemistry!
If it was for the 2OH, it was because the 2 aswell. The constant is multiplied with the X for the ice table but it is also used as the power for the ksp equation. I could be wrong though but thats what im understanding
Thank you !! However, I have a question. I understand that for (OH)2 in Ca(OH)2, 2 is the coefficient for OH and becomes its exponent when calculating Ksp. How do you decide to use the subscript as a coefficient. I was wondering why in the last question PbI2, 2 was used as the coefficient? The reason why I am confused was because in the CaCO3 example, 3 was not used as a coeeficient : just [Ca][CO]?
This may be a bit late but that's because carbonate is a polyatomic ion. CaCO3 is one calcium (Ca) and one carbonate (CO3). If it were Ca(CO3)3 then there would be three carbonate ions and the exponent would be 3, [Ca][CO3]^3. This means that the Ksp expression would be Ksp=(x)(3x)^3. Because the carbonate is not separating into individual molecules, it is functionally just another ion, similar to iodine.
(2x)^2 is the same as 2x times 2x, so you can solve that part by multiplying the 2's and the x's together, making 4x^2. Then you multiply that by the last x which makes 4x^3. Hope that helps!
Basically, the subscript becomes the coefficient since the amount of iodine being dissolved is two per molecule. And then using what you learned about icebox earlier you just apply the same concepts. At least that’s what I got out of it.
@@marislox1844 I don’t understand why a few people not being able to understand the explanations provided in the video automatically discredits “this person’s” entire channel. If anything, ask for whatever wasn’t understood to be cleared up.

Can you explain calcium phosphate kidney stones formation through solubility product? I am a pediatrician and find it a bit difficult Thanks in advance 🙏
all equilibrium constants are unitless, they are just ratios of activity compared with a reference value, try not to think in terms of dimensional analysis
@@ProfessorDaveExplains I'm not sure I'm following your last comment. Equilibrium constants units are usually dependent on the specific reaction. Yes sometimes it can be unitless, if the molar quantity of reactants equals the molar quantities of the products. But they can also have units if the molar quantities are not equal. Thank you very much for your videos. They are very effective summaries.

@@ProfessorDaveExplains So are diatomic rules ignored when you break down a ionic compound?
It's just a totally different compound. It has nothing to do with this one.

Hi, a question: When one of the ions in the equlibrium concentration is, for example, 2x, why should also be squared?
If it was for the 2OH, it was because the 2 aswell. The constant is multiplied with the X for the ice table but it is also used as the power for the ksp equation. I could be wrong though but thats what im understanding

Because the carbonate is not separating into individual molecules, it is functionally just another ion, similar to iodine.

Hey Proffesor ! It's nice to bump into you again..
I hate chemistry but it seem less intimidating with this guy, thanks sir :3
Great work 👍👍👍
for 7:00 why is the Ksp 4x^3 and not 2x^3 ??
(2x)^2 is the same as 2x times 2x, so you can solve that part by multiplying the 2's and the x's together, making 4x^2. Then you multiply that by the last x which makes 4x^3. Hope that helps!
Yes I'm confused too

Thank you professor Dave. 👍👍👍👌👌👌
How did you get the 2.6 * 10 ^-3? I know what the single X comes from but not the concentration of Iodine.
If he knew what he was talking about, he would have explained. I suggest not wasting your time with this person's videos.

Why we raise the power of concentration by its stoichiometric coefficient?
Please explain

Thank u sir so much now i know how to make ICE chart💖

wait what do you mean by ''unitless equilibrium constant''? equilirium constants may have units..
at 6:06 how didi you solve for the 7.9×10^-5?
Square root

thanks mister
Could you please make a video on Organometallic Chemistry?
Why is the OH value doubled AND squared?
Did u get it yet?
I dont get it either
thanks very much
Thx alot !!
What about the solubility of iron(II) hydroxide in a. Solution of ammonia solution
I have a question: Why did you use solid compound I thought you can't use it or how does it work?
why to raise the molarity to the power of stoichiometric component?
Thank u very much!!
“This model is an oversimplification that serves the purpose of the moment” = all chemistry until Schrodinger and statistical thermodynamics 😂
why does adding a solid not affect the equilibrium constant ?
Can you explain calcium phosphate kidney stones formation through solubility product?

Thanks in advance 🙏
Why dont we consider solid reagents?
Hello, sir. What will happen to the solubility of BaSO4 if NaCl is being added, and why? Thank you so much.
Thx, you are great
so when you're given Ksp of the reactant and find the solubility of the other products, how do you take pOH from that?
thank you for simple explanation ♥️
you out here carrying my grade
does this mean if the human body is in touch with distilled water u solute a tiny tiny amount into it?
Can anyone explain why the book Ksp values very between different resources (even for the same temperature)?
Good
4:46 can anyone tell what does he mean by unitless as in my book the units for concentration are given as mol×dm^3
@Omar Eshdooh no im pretty sure its in mol per dm cube i can send you pics of the questions
@Omar Eshdooh yeah its actually a level chemistry equations by jim clark. Chapter 9. Look at the examples.
This video helped me a lot. But the intro killed me.
How do you know how many ions it dissolves to?
just split it up into individual ions
I did not focus on this video, just his neck.
Right🤣🤣🤣
Am really confused how did u get the 1.3×10^-9 like i mean what do u write in the calculator to get that result?
Thank you 😇 Dave ... .
Mark my words foreign teachers are the best
Why some AgCl soluble
@professorDaveExplains DId you say Ksp has no units? How is that possible? moldm-3 xmoldm-3 = mol2dm-6 for example
all equilibrium constants are unitless, they are just ratios of activity compared with a reference value, try not to think in terms of dimensional analysis
@@ProfessorDaveExplains this has never been my understanding. What are your thoughts here www.chemguide.co.uk/physical/ksp/calculations.html
hmm perhaps you're looking at molar solubility values
