Embibe Experts Solutions for Chapter: Qualitative Analysis, Exercise 1: EXERCISE-1

If NaOH is added to an aqueous solution of zinc ions, a white precipitate appears and on adding excess NaOH, the precipitate dissolves. In this solution, zinc exists in the:

Which one of the following statement is correct

A pale green crystalline metal salt of $\mathrm{M}$ dissolves freely in water. On standing it gives a brown $\mathrm{ppt}$ on addition of aq. NaOH. 

The metal salt solution also gives a black precipitate on bubbling H₂S in aqueous medium. An aqueous solution of the metal salt decolourises the pink colour of the permanganate solution. The metal in the metal salt solution is:

The salt used for performing 'bead' test in qualitative inorganic analysis is?

Which is not dissolved by dil. $\mathrm{HCl}$?

When ${\mathrm{H}}_2\mathrm{S}$ is passed through ${\mathrm{Hg}}_2^{2+}$, we get

Sometimes yellow turbidity appears while passing ${\mathrm{H}}_2\mathrm{S}$ gas even in the absence of II group radicals. This is because of 

A metal salt solution gives a yellow $\mathrm{ppt}$ with silver nitrate. The $\mathrm{ppt}$ dissolves in dil. nitric acid as well as in ammonium hydroxide. The solution contains
