Question

what is deionise water? how can we remove permanent hardness of water. suggest 2 methods

Answer 1

Answer:

Deionized (DI) water is water that has been treated to remove all ions – typically, that means all of the dissolved mineral salts. Distilled water has been boiled so that it evaporates and then re-condensed, leaving most impurities behind.

Answer 2

Answer:

deionised water contains no ions causes hardness of water.

Explanation:

methods to remove hard ness of water

1. use resins to remove hardness of the water sample.
2. by using the water softener. There are different water softeners available in the market and they are regarded as ion exchange systems. In such systems, it is the hardness ions that are exchanged for salt (sodium or potassium) ions. The exchange is done within the resin tank of the water softener and the process is explained like it comes in contact with small resin beads, which are covered with salt ions. In the water softening process, the water flows through the resin beads and the hardness of ions trade places with salt ions. Water softening is a technique that easily removes ions and makes hard water soft.
