Question

How does an acid react with metal carbonate? Give ab example.

Answer 1

$<b>$
• When an acid reacts with a metal carbonate, a salt, water and carbon dioxide are produced:

$Acid + Metal\: carbonate \rightarrow salt + water + carbon\: dioxide$

• The salt that is produced depends upon which acid and which metal react.

$Example:$

• $CaCO_{3}$ is a Metal Carbonate
When $CaCO_{3}$ reacts with dilute hydrochloric acid ,forms carbon dioxide gas & solution of calcium chloride.

•Calcium Carbonate reacting with HCl to form Calcium Chloride, Water and Carbon dioxide.

• $CaCO_{3} + 2HCL \rightarrow CaCl_{2} +H_{2}O+CO_{2}$

Answer 2

When metal carbonates react with acid they give metal salt , water and carbon dioxide .

Na2Co3 + H2SO4 ----- Na2SO4 +

H2O + CO2
