Which one of the following methods is most suitable for preparing deionized water?

Options

ASynthetic resin method
BCalgon's method
CClark's method
DPermutit method

Correct answer

A. Synthetic resin method

Step-by-step solution

Pure de-mineralised (de-ionised) water free from all soluble mineral salt is obtained by passing water successively through a cation exchange and an anion exchange resins. 2 RH ( S ) + M 2 + ( aq ) ⇌ MR 2 (   S ) + 2 H + ( aq )
