Question

Describe the method of softening of water by permutit process

Answer 1

Answer:

The most common water softening method is called “ion exchange.” Put simply, this type of softening is a process where calcium and magnesium (the minerals that make water hard) ions are exchanged for sodium ions. This exchange takes place in a “resin bed” made up of a tiny bead-like material

Answer 2

Answer:

By the permutit process temporary and permanent both types of hardness can be removed

Explanation:

In this method, hydrated sodium- alumino sillicate (Na2Al2SiO8) or sodium zeolite is used. The chemical is represented by Na2Z. When temporary or permanent hard water is treated with sodium zeolite, the calcium salts of the hard water changes into sodium salt and the sodium zeolite gradually changes into calcium or magnesium zeolite.
