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.

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.

Hi Professor Dave, why wasn't the Ba3(PO4)2 compound split up?

water insoluble, forms a precipitate
@rup38088 жыл бұрын
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!

yep it's highlighting the chemistry that occurs, like the formation of a precipitate.

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 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.
@ProfessorDaveExplains4 жыл бұрын
This method is how you know which ions to put on the left.
@banderfargoyl4 жыл бұрын
@@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.
@ProfessorDaveExplains4 жыл бұрын
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.

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