### CH3COOH acid/base identifying

How can I know that CH3COOH wants to donate its proton to create H3O+ and CH3COO- without memorizing that it is an acid from the table in the book? I want to know how to identify them so I can write chemical equations when needed to do ICE tables for weak acids and bases. Thank you? Also will it always be the molecule + H2O<-> the product side when writing these equations for ICE tables? Thank you!

### Re: CH3COOH acid/base identifying

I believe that typically when a molecule contains a nitrogen, it will accept a proton and create the hydroxide ion. If not, then the molecule it will donate the proton to create a hydronium ion. You should probably memorize the few strong acids though, like HCl.

Secondly, you don't have to include the H2O in your ICE table, but generally speaking, it will be reactants $\leftrightarrow$ products.
