Q. Three cations

A, B, C

are allowed to react with ammonium hydroxide solution.

A

and

B

produce a dirty green precipitate and a reddish brown precipitate respectively, both of which do not dissolve on further addition of

{N H}_{4} O H

C

gives pale blue colour precipitate with less amount of ammonium hydroxide and on further addition of

{N H}_{4} O H

, precipitate becomes soluble and deep blue colour solution is formed:

NH₄OH + FeCI₃ → NH₄CI + Fe(OH)₃

To balance the above equation, the coefficient for ammonium hydroxide and ammonium chloride will be:

On addition of ammonium chloride to a solution of ammonium hydroxide

Q. Assertion :On addition of

{N H}_{4} C l

{N H}_{4} O H

solution,

p H

decreases but remains greater than

7

. Reason: Addition of

{N H}_{4}^{+}

ion decreases ionisation of

{N H}_{4} O H

thus

[{O H}^{-}]

is decreased hence,

p H

decreases.

Q. When

{N H}_{4} C l

is added to

{N H}_{4} O H

solution, the dissociation of ammonium hydroxide is reduced. It is due to:
