The precipitate formed from the reaction of lead salts with aqueous ammonia solution is insoluble in excess ammonium hydroxide solution.

Q.

When lead nitrate reacts with ammonium hydroxide, a chalky white precipitate is formed. The precipitate formed is insoluble in excess of ammonium hydroxide. Name this precipitate.

Q. Assertion :We can distinguish between $Z{n}^{2+}$ and $P{b}^{2+}$ using ammonium hydroxide solution. Reason: Zinc ions with ammonium hydroxide gives white precipitate of zinc hydroxide which dissolves in excess of ammonium hydroxide. Aqueous solution of lead salt do not show any change on treatment with ammonium hydroxide

Q. Assertion :Reaction of liquor ammonia with nitric acid is a neutralization reaction. Reason: Ammonia in the gaseous form or in aqueous solution as ammonium hydroxide neutralizes the nitric acid forming the respective ammonium salts.

Q. Precipiate formed on reaction of zinc salts with ammonium hydroxide is soluble in an excess of ammonium hydroxide solution.

Q. Assertion :White precipitate of $Mg(OH{)}_2$ is insoluble in excess of sodium hydroxide but readly soluble in solution of ammonium salts. Reason: $Mg(OH{)}_2$ is very sparingly soluble in water.
