What I have realized is that, with chemistry you have to understand what is actually happening rather than memorizing equations. I had a rough time with the first chemistry class I took in college because of this. my brain was not trying to understand chemistry. but now taking analytical Chem I am struggling a bit because as easy as the basics are, youre making it easier for me to go back and recall certain concepts and force me to understand conceptually and understand why everything is happening!!
Any teacher who isn't teaching chemistry by explaining what is going on is doing it wrong. As a chemistry teacher I am sorry it was done wrong in your basic classes.
I wish I had found you on my first semester of chem! Anyways, I sincerely appreciate your videos. You do a wonderful job of bridging the gap between too lame to learn anything and too complex to understand!
Hey Professor Dave, so the compounds in solid phase do not cancel in the ionic equation because they are not soluble? Also - is the purpose of ionic equations to isolate the ionic reactants that come together (in this case synthesize) to form a compound? Cheers!
@@ProfessorDaveExplains I must be missing something here. If you don't know the ionic composition of compounds then you can't write out an ionic equation. But if you do know this, then you can just decompose the precipitate and put the ions of the left, since any ion that doesn't precipitate is a spectator.
If you have a shortcut that's fine, but students learning this concept need to see the compounds dissociate to conceptualize what's going on in solution, and identify the ones that comprise the precipitate.
@@ProfessorDaveExplains NP. I find your explanations to be first rate on those topics I know something about. But I'm not a chemist, and I should have phrased my first comment as a question.
Hi professor, you should perhaps mention how to write net ionic equation if you have weak acid or base included. Rules are slightly different when they're involved.
Sir we have a method to determine a single replacement reaction Will happen or not by the help of metal reactivity series but how to know a double replacement reaction Will happen or not
We often say particles(Na+ or Cl-) move freely in solution. What it mean? As H2O surrounds these ions, then whether these ions form and break again & again or the H2O molecules move freely and So they pull these ions with itself(H2O).
you know those ball pits that kids play in where all the balls can shuffle around? it's like that, they are all just constantly changing position with respect to each other.

Speaking of
Some teachers say you've got to memorize in science class or you won't pass.
I once had a teacher like that
Professor Dave is my real chem professor cuz I dont know anything thats going on in ny lectures and he's just so helpful
same here
ugh wish I had discovered you sooner !!! please make more !!!!
go to my channel home page to see everything i've done so far! lots more general chemistry for you.
YOUR PAGE IS AMAZING I've BEEN WATCHING SINCE HIGHSCHOOL AND NOT IT IS SUPER HELPFUL FOR ONLINE SCHOOL!!!!!!!! thank you!!!!!
I wish I had found you on my first semester of chem! Anyways, I sincerely appreciate your videos. You do a wonderful job of bridging the gap between too lame to learn anything and too complex to understand!
my test is 1 month from now and you are helping me so much thx so much you explain insanely good
Thank you so much Prof. Dave! I love your videos.
Thank you again lumberjack chemistry jesus
I AM 7TH GRADE AND LOVE STUDYING 10 AND 11TH STUFF. YOU HELP ME SO MUCH.
Love you man u really come in clutch
I think a 12 yr old can understand this because of the simple explanation
I know I am super late at questioning but how do u determine whether to put positive or negative?

yep it's highlighting the chemistry that occurs, like the formation of a precipitate.
Hi Professor Dave, why wasn't the Ba3(PO4)2 compound split up?
water insoluble, forms a precipitate
You don't need to write out the full ionic equation and cancel. You can just put the precipitate on the right and its ions on the left.
This method is how you know which ions to put on the left.

No no, you're absolutely right, it's just that this is the way the concept should be initially taught.

Impeccable sir
How benzene can dissolve many compounds if it cannot make dipole dipole interactions?
it can dissolve other nonpolar substances! nonpolar dissolves nonpolar.
thank you so much professor! but why don't we split CaCO3 at the product of equation?
규링 calcium carbonate is insoluble, so it won’t dissociate.
Thanks

if you swap components and get a new substance that is water insoluble, it will precipitate. if not, everything just sits in solution.

Good
Handsome and smart man
How how can i know they will stay as ( aq ) as they were ?
You have to memorize the solubility chart for this...
Yeah roast those lazy spectator ions. Tey don't even do chemistry. 😂😝
Thank u Science Jesus
