Industrial Chemistry - Hardness of water
Hardness 96,699 Water can be classified as hard water and soft water. Soft water: It lathers with soap. Water which is obtained from the rains is soft water. This water is suitable for household purposes, for example, laundry and cleaning. Hard water: It is known as hard water because of the presence of calcium and magnesium salts. Hard water does not lather with soap but instead forms a precipitate. ⇒ Check: Differences between Hard Water and Soft Water Table of Content What Is Hard Water? Types of Hardness of Water Disadvantages Remove Temporary Hardness Remove Permanent Hardness Harmful Effects of Hard Water What Is Hard Water? Hard water has high mineral content. It is formed when water percolates through the deposits of chalk and limestone, which are made up of magnesium and calcium carbonates. It does not lather with soap, so it is not suitable for laundry purposes. The hardness of water is harmful to the boilers as the deposition of salts occurs, which reduces the effi...
