Question

what happens when an acid reacts with a metal carbonate write balanced equation

Answer 1

$\bf\:{\underline{Answer}}:-$

When carbonate reacts with acid , it forms corresponding salt, CO2 & H2O. Sodium carbonate ( Metal carbonate) reacts with hydrochloric acid, it forms sodium chloride salt , carbon dioxide & water.If the salt formed is water-soluble, the colourless solution turns to the colour of the metal ion(aq).

Answer 2

Hello :D ✨

Explanation:

When an acid reacts with a metal carbonate a salt, carbon dioxide and water are formed. ... Hydrochloric acid reacts with calcium carbonate to form calcium chloride, carbon dioxide and water.

Acid + Metal carbonate ⟶ Salt + Water + Carbon dioxide

CaCO 3(calcium carbonate-metal carbonate) + 2HCl ⟶ CaCl 2 (calcium chloride-salt) + H 2O + CO2
