Question

What kind of reaction is represented by carbonate + acid -> salt + water + carbon dioxide?

Answer 1

This is an acid base reaction.

Explanation:

`CO_3^(2-) + 2H^+ rarr H_2O + CO_2(g)uarr`

The weak base, carbonate, reacts with 1 or 2 equivalents of acid to give `HCO_3^-` or `H_2CO_3`, i.e. hydrated carbon dioxide, `H_2O*CO_2`.
