Question

What are the advantages of hard water.

Answer 1

Advantages of hard water:

Water free from dissolved salts has a very flat taste. The presence of salts in hard water makes it tasty. So, hard water is used in making beverages and wines.

Calcium and magnesium salts present in small amounts in hard water are essential for bone and teeth development.

Hard water checks the poisoning of water by lead pipes. When these pipes are used for carrying water, some lead salts dissolve in water to make it poisonous. Calcium sulphate present in hard water forms insoluble lead sulphate in the form of a layer inside the lead pipe and this checks lead poisoning.
