Question

By Which Method Temporary Hardness Of Water Can Be Removed

Answer 1

Answer:It can be removed by either processes: boiling or by adding washing soda to the temporary hard water.

Explanation:

1. By Boiling:

Mg(HCO3)2 = H20 + CO2 + MgCO3

The magnesium carbonate will be precipitated and will not cause any hardness in water.

2. By Adding Washing Soda:

Mg(HCO3)2 + Na2CO3 = MgCO3 + NaHCO3

Here, the liquid will be rendered soft as the precipitate will not cause any hardness in water.

Hope this helps
