Class 11 NEET Chemistry Equilibrium Questions Part 1

NH4OH is a weak base but HCl is a strong acid in solution, so pH of NH4Cl solution is comparatively low.
NaNO3 is a salt of strong base and strong acid, so pH of the solution will be 7 .
Hydrolysis of potassium acetate (a salt of a weak acid and a strong alkali) gives a weakly alkaline solution, since the acetate ion acts as a weak base.
The pH of this solution ≈8.8.
Hydrolysis of sodium carbonate (a salt of strong alkali and a weak acid) gives an alkaline solution
The pH of this solution is >10.
