Uses of Calcium Carbonate

Write equatio...

Question

Write equation for the reaction which take place when excess of gas X dissolves white precipitate Y to form a soluble compound Z.

Open in App

Solution

X is carbon dioxide. Y is calcium carbonate.
The reaction which takes place is given as:
$C a C O_{3 (s)} + H_{2} O_{(l)} + C O_{2 (g)} \to C a (H C O_{3})_{2 (a q)}$
