Hard water when passed through ion exchanger containing resin $R S O_{3} N a$ group becomes free from:

Question

Hard water when passed through ion exchange resin containing RCOOH group- becomes from -Cl-SO-4-2-H-3-O-Ca-2-

Toppr Admin · Accepted Answer

Hard water contains Ca and Mg salt so when it is passed through negative ion exchange resin- it capture cations from water and make it free from Ca-2-

Hard water when passed through ion exchange resin containing $R C O O H$ group, becomes free from :
$C l^{-}$
$S O_{4}^{- 2}$
$H_{3} O^{+}$
$C a^{+ 2}$

Hard water contains $C a$ and $M g$ salt so when it is passed through negative ion exchange resin, it capture cations from water and make it free from $C a^{+ 2}$ .

Hard water when passed through ion exchange resin containing RCOOH group, becomes free from :Cl−SO−24H3O+Ca+2

Hard water contains Ca and Mg salt so when it is passed through negative ion exchange resin, it capture cations from water and make it free from Ca+2.

Hard water when passed through ion exchange resin containing $R C O O H$ group, becomes free from :
$C l^{-}$
$S O_{4}^{- 2}$
$H_{3} O^{+}$
$C a^{+ 2}$

Hard water contains $C a$ and $M g$ salt so when it is passed through negative ion exchange resin, it capture cations from water and make it free from $C a^{+ 2}$ .
