Hi Guys. This is more chemistry than physics but maybe you can help.
I am having a hard time find out what (salt) will appear as a product, in an acid-carbonate reaction.

Example from my textbook: HC2 H3 O2 + K2 CO3 --> CO2 + H20 + (salt)

We know that it will always give Carbon Dioxide and Water, and a salt.

How do i find out what the salt is?? The full balanced answer for the salt is 2 KC2 H2 O2 but i don't know how to obtain that!

I know for acids-base, we must take the cation of the base and the anion of the acid.. but in this case? Let me know, thanks :)

For organic acids, it is helpful to write them out to emphasize their structure. For example, acetic acid (HC2 H3 O2 in your notation) is more clearly written as CH3COOH, which dissociates into acetate ions and a proton: CH3COO- + H+.

The salt remaining after the reaction is potassium acetate (K+ CH3COO-).
