Question

Name two insoluble carbonates. Write the equation when calcium carbonate reacts with sulfuric acid.

Answer 1

Two Insoluble carbonates

• Barium carbonate $\left({\mathrm{BaCO}}_3\right)$
• Magnesium carbonate $\left({\mathrm{MgCO}}_3\right)$

Reaction summary:-

When calcium carbonate $\left({\mathrm{CaCO}}_3\right)$ reacts with Sulfuric acid $\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$, the formation of a precipitate, Calcium sulfate $\left({\mathrm{CaSO}}_4\right)$ along with water $\left({\mathrm{H}}_2\mathrm{O}\right)$ and carbon dioxide $\left({\mathrm{CO}}_2\right)$ take place.

Balanced chemical equation

${\mathrm{CaCO}}_3\left(\mathrm{s}\right)+{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)\to {\mathrm{CaSO}}_4\left(\mathrm{s}\right)+{\mathrm{CO}}_2\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$
