Softening of hard water is done using sodium aluminium silicate
(zeolite). This causes
Show answer and solution
Softening of hard water: Ion exchange resins used for
softening of hard water is based upon selective and competitive
adsorption of ions on resins.
The organic polymers containing groups like -COOH, -SO3H and -NH2
etc. possess the property of selective adsorption of ions from
solution. These are quite useful in the softening of water.
