Why aqueous nacl is neutral while nh4cl is acidic in nature?

Answer 1

nh4cl breaks into ammonium hydroxide and hcl and for hcl is a strong acid the salt is acidic and in nacl case naoh and hcl are formed which are strong base and acid respectively so it is neutral

Answer 2

Ammonium Chloride (NH4Cl) is a salt of a strong acid (HCl) and a weak base (NH4OH). Hence, in an aqueous solution, it shows acidic properties.

When mixed with water, it gets hydrolysed as follows.

NH4Cl + H2O ---> NH4OH + HCl

The salt and the strong acid (HCl) get ionised while the weak base (NH4OH) remains unionised.

NH4+ + Cl- + H2O ---> NH4OH + H+ + Cl-

Cancelling the Cl- ions from both sides.

NH4+ + H2O ---> NH4OH + H+

TheÂ?H+Â?ions left in the solution gives the solution it's acidic properties.

Answer 3

Aqueous NaCl is neutral because NaCl dissociates completely into Na+ and Cl- ions, neither of which react with water to produce acidic or basic species. On the other hand, NH4Cl hydrolyzes in water to form NH4+ and Cl- ions. The NH4+ ion can protonate water to form H3O+ ions, resulting in an acidic solution.

Answer 4

The ammonium ion will tend to release a hydrogen ion, making the solution slightly acidic.
