Question

Study help, please? I've a test in chemistry next week on acids, bases, and salts.

Answer 1

I was sick all last week, so I missed a lot of the key points my teacher made in class. I have a review sheet, but I don't understand the majority of it. Would someone mind helping me?

Answer 2

well, that's a bit vague, acid/base chemistry is a very large field since most reactions are acid/base reactions. Especially in organic chemistry. Can you be a bit more specific? I can give you a quick yet detailed review on some concepts, but w/o a specific topic in mind, I can't really help you much.

Answer 3

I was going to post some questions once I got a reply. Thank you!!
One thing I'm pretty confused about is balancing reactions. This one is listed:

NaOH + Hl -> ___ + ___

In the slots I filled in HOH + NaI, though I'm not sure if that's right, and I'm not even sure how to come about balancing it.

Answer 4

Well, you are correct. It might be easier if you separated them by charge. Since you know positive is attracted to negative. It's all you're really doing.
For instance in your example, you have: \(Na^+ OH^- +H^+I^- \rightarrow Na^+I^- + H^+ OH^- =NaI + H_2O\)

Answer 5

This might now be the best example, but to check if it's balanced, you have to see if the same amount is on both sides. meaning, there must be 1 sodium, 1 oxgen, 2 hydrogens and 1 iodide on BOTH sides (prduct and reactant).

Think of it like this

2 slices of bread + 1 cheese -> cheese sandwich
but if you think about it, u get a new product, but there's STILL two slices of bread there. one of the slices just didn't disappear. which is what occurs in a reaction. the atom just doesnt disappear. it must also be includes so other people know the ingredients and how to prepare a "cheese sandwich"
