How to know if something dissolves into an Acid or Base

Postby Natalie Yakobian » Sat Nov 21, 2015 10:49 pm

HI,
If you are given a reaction and asked if it is a acid/base reaction do you have to take into account whether or not the chemical compounds are soluble? Should we memorize solubility rules?

For example question 12.9 asks us to write the net ionic equations.

In general acids and bases are polar and therefore soluble in water, solubility rules that you may have had to memorize for AP chem are more for salts.

In determining whether a molecule will dissolve to form an acidic or basic solution, it is easiest to write out a chemical equation in which the molecule reacts with water. When you do this, it should generally be clear what type of solution you will have based on the resulting products. If the reaction could go either way, you may have an amphoteric molecule.
