Odisha Board Solutions for Chapter: s-Block Elements:Alkali and Alkaline Earth Metals. Alkaline Earth Metals (Group-2), Exercise 1: QUESTIONS

Explain the following phenomenon by means of balanced equations. 

When exhaling is made through a tube passing into a solution of lime water, solution becomes turbid. 

Explain the following phenomenon by means of balanced equations. 

When exhaling is made through a tube passing into a solution of lime water, solution becomes turbid. The turbidity of this solution eventually disappears when continued exhaling is made through it.
 

Explain the following phenomenon by means of balanced equations.

When exhaling is made through a tube passing into a solution of lime water, solution becomes turbid. When continued exhaling is made through it, turbidity of this solution eventually disappears and calcium hydrogen carbonate is obtained. When it is heated turbidity reappears.
