Saleha Pervez and Shikha Goel Solutions for Chapter: Analytical Chemistry: Uses of Sodium and Ammonium Hydroxides, Exercise 4: ARCHIVES*(Last 6 Years)

Choose the correct answer from the options given below. The salt solution which does not react with ammonium hydroxide is

A chloride which forms a precipitate that is soluble in excess of ammonium hydroxide, is

State relevant observation. Action of sodium hydroxide solution on ferrous sulphate solution.

Identify the substance underlined cation that does not form a precipitate with ammonium hydroxide but forms one with sodium hydroxide.

How will you distinguish between ammonium hydroxide and sodium hydroxide using copper sulphate solution?

Identity the salts $\mathrm{P}$ and $\mathrm{Q}$ from the observations given below:

On performing the flame test salt $\mathrm{P}$ produces a lilac coloured flame and its solution gives a white precipitate with silver nitrate solution, which is soluble in ammonium hydroxide solution.

Identity the salts $\mathrm{P}$ and $\mathrm{Q}$ from the observations given below:

When dilute $\mathrm{H}\mathrm{C}\mathrm{l}$ is added to a salt $\mathrm{Q}$, a brisk effervescence is produced and the gas turns lime water milky. When $\mathrm{N}{\mathrm{H}}_4\mathrm{O}\mathrm{H}$ solution is added to the above mixture (after adding dilute $\mathrm{H}\mathrm{C}\mathrm{l}$), it produces a white precipitate which is soluble in excess $\mathrm{N}{\mathrm{H}}_4\mathrm{O}\mathrm{H}$ solution.

_____ $\left(\mathrm{AgCl}/{\mathrm{PbCl}}_2\right)$, a white precipitate, is soluble in excess $\mathrm{N}{\mathrm{H}}_4\mathrm{O}\mathrm{H}$.
