Question

The chemical name of the permutit is:
A. Potassium aluminium sulphate
B. Calcium super phosphate
C. Sodium aluminium silicate
D. Sodium meta aluminate

Answer 1

For solving this question, we need to understand the process of permutit. The chemical reaction of permutit is a process in which hard water contains ions such as $C{a^{2 + }}$ and it is filtered with the help of natural sand called the zeolite.

Complete step by step answer:

As we know, permutit is a zeolite of an artificial source. It is a type of ortho silicate of sodium aluminium compound. It is known to be the trade name of a mixture of hydrated silicates of Al and Na which contains ions such as $C{a^{2 + }}$ and it is filtered with the help of natural sand.
Basically, we need to remember that permutit is a manmade zeolite. Thus, it is used to remove the hardness of the water as the zeolite contains Sodium $Na$ and Aluminium $Al$ that makes the water soft in nature. Also, calcium $Ca$ and Magnesium $Mg$ are mainly responsible for the cause of hardness of the water.
Hence, the chemical formula of this Sodium aluminum compound is $N{a_2}A{l_2}S{i_2}{O_8}.x{H_2}O$.
Thus, permutit is the chemical name of Sodium aluminium silicate (option C). The permutit is industrially used for softening hard water and refining sugar.
Therefore, the option C is correct.

Note:
We need to know that highly acidic water is not suitable for use in light. So, for softening of water with the help of the zeolite process, hard water is percolated at a specified rate through a bed of zeolite. As zeolite contains sodium ions that are loosely packed and is represented as $N{a_2}Z$.Here, Z represents an insoluble radical framework.
