Question

Which salt solution doesn't react with ammonium hydroxide ?
a. Calcium nitrate
b. Zinc nitrate
c. Lead nitrate
d. Copper nitrate

Answer 1

The answer is a) Calcium nitrate.

The salt solution that doesn’t react with ammonium hydroxide is calcium nitrate.

When ammonium hydroxide solution is added to calcium nitrate, there is no change to either of the compounds. This is because no reaction takes place between them. As a result, there is no formation of a precipitate or any other kind of compound.
