Question

When gas is formed on heating limestone is passed through freshly prepared lime water, the lime water turns milky??? .. . Give scientific reason

Answer 1

When Carbon dioxide is passed through Lime water or Calcium Hydroxide, it turns milky due to the formation of the Precipitate of the insoluble milky Calcium Carbonate.

Answer 2

$\large\boxed{\fcolorbox{blue}{yellow} {Answer}}$

1. When limestone is heated, calcium oxide and carbon dioxide are formed.

2. This carbon dioxide gas is passed through freshly prepared lime water, insoluble calcium carbonate and water are formed.

In this reaction, lime water turns milky.

$\large\boxed{\fcolorbox{blue}{yellow} {Chemical Equation }}$

Ca(OH)2 + CO2 ⟶ CaCO3 ↓ H2O

Calcium Carbon Calcium Water

Hydroxide dioxide carbonate
