Hard water is water that has a large amount of minerals like salts of magnesium and calcium in it. It is formed when the water stream passes through limestone and chalk deposits made up of calcium and magnesium carbonates. When hard water is boiled, it leaves a coating of lime on the inner side of the utensil. Usage of hard water leads to damage in the industrial set-up as it is liable to cause break-down in boilers, etc. Other disadvantages of using hard water are that the soap lather doesn’t form easily; it leaves a coating in water heaters, utensils, etc. Even hair washed in hard water may feel sticky and look dull.
