Difference Between Hard Water And Soft Water

Water is a universal solvent. It is a chemical substance which is transparent, colorless, odorless and tasteless. Water is categorised in two types. They are hard water and soft water. These two types are not differentiated based on their touch and feel or appearance. This difference is based on the mineral content of each.

Hard water:

The water with naturally present minerals like magnesium and calcium with detectable amount is called hard water. These minerals are beneficial for health. They add flavour to hard water.

Soft water:

It is treated water. It is left with only cations and that is sodium. It has a salty taste.
