A chemical process in which water combines with salt so that its pH change from 7 acid and base are formed is called hydrolysis,
NaCl + H2O ————>NaOH + HCl
CASE – 1:
It pH increases:
When water is combined with basic salt, strong base and weak acid are formed so that the pH of solution increases.
Na2CO3 + 2H2 ————>NaOH + H2CO3
CASE – 2:
If pH decreases:
When water is combined with acidic salt, strong acid and weak base are formed so that the pH of solution decreases.
NH4CL + H20 ————-> NH4OH + HCl
CASE – 3:
If negligible change produces in pH:
When water is reacted with neutral salt negligible change is produce in the pH of solution as strong acid and strong base are formed.
KCI + H20————-> KOH + HCl
