Answer 2

Answer:

Hard water doesn't form foam with water.  

Explanation:

• The hardness of water is either temporary or permanently it is depends of the dissolved salts present in it.

Depending upon the 'types of salts' dissolved in the water, hardness of the water can be divided into two types:

1. Temporary hardness – caused by "Calcium and Magnesium bicarbonates".
2. Permanent hardness- Caused by "Calcium and Magnesium chlorides and sulphates".

• Soap is less work in hard water as it reacts to the soap's organic acid forming "calcium or magnesium salt". These salts are insoluble.
