Question

How is the neutralizsation of a carbonate with an acid different from the neutralisation of an oxides or a hydroxide?

Answer 1

Answer:

Neutralization of carbonate with acid will lead to formation of salt, water and evolution of carbon-di-oxide gas.

Metal Carbonate + Acid → Salt + Water + CO2

For example,

Na2CO3 + 2HCl → 2 NaCl + H2O + CO2

However, neutralization of oxide or hydroxide with acid will lead to formation of salt and water only.

Metal Oxide + Acid → Salt + Water

Na2O + 2HCl → 2 NaCl + H2O

Metal Hydroxide + Acid → Salt + Water

NaOH + HCl → NaCl + H2O

Answer 2

Answer:

The reactions between carbonates and acids are called neutralization reactions because the acid is neutralized.A carbonate is negatively charged and contains a carbon bonded to three oxygen atoms. The general reaction results in a salt, carbon dioxide gas, and water.
