Hard And Soft Water

HARD WATER hard water is water in which soap does not lather well.

DISADVANTAGES OF USING HARD WATER

using hard water is a disadvantage as the bicarbonates and sulphates which are the common salts which form hardness in water form an insoluble layer called fur or scale. as a result of this the water takes more time to get boiled,the fabric may get spoiled fuel is wasted etc

SOFT WATER water in which soap lathers well is called soft water

HOW TO MAKE HARD WATER SOFT?

We can make hard water soft by boiling it. The insoluble bicarbonates dissolve into soluble carbonates.We can also treat hard water with washing soda {sodium carbonate=Na2CO3}.
