Answer 2

Answer:

In aqueous solution, salts breakdown into their constituent acid and base, called salt hydrolysis.

Aqueous Sol. of ammonium chloride -

NH4Cl + H2O ======> HCl + NH3

HCl is strong acid therefore solution is acidic.

Aqueous Sol. of sodium chloride -

NaCl + H2O =======> HCl + NaOH

HCl is strong acid and NaOH is strong base therefore they neutralizes each other and Sol. becomes neutral.
