Which of the following sulphates are soluble in water?

$0.33\mathrm{M}$ solution of aluminium chloride $\left({\mathrm{AlCl}}_3\right)$ is used for the quantitative analysis of ${\mathrm{Al}}^{+3}$ ions. If $\mathrm{NaOH}$ is added in $0.33 \mathrm{M} {\mathrm{AlCl}}_3$ a while ppt is formed and when excess $\mathrm{NaOH}$ is added it dissolved by forming soluble tetrahydroxoaluminate ion ${\left[\mathrm{Al}(\mathrm{OH}{)}_4\right]}^{-}$, if ${\mathrm{NH}}_4^{+}$ ions are added to $\mathrm{Al}(\mathrm{OH}{)}_4^{-}$, then

Tin (II) ion is used in identification of mercury (I) or mercury (II) ion in the qualitative analysis of basic radical. Select the correct statement about this experiment.
Experiment : ${\mathrm{Hg}}^{+2}+{\mathrm{Sn}}^{2+}⟶$

The number of intramolecular hydrogen bondings in $\mathrm{Ni}(\mathrm{DMG}{)}_2$ complex

An aqueous solution of a mixture of two inorganic salts. When treated with dilute $\mathrm{HCl}$ gave a precipitate of $\left(\mathrm{P}\right)$ and a filtrate $\left(\mathrm{Q}\right)$. The precipitate (P) was found to dissolve in hot water. The filtrate $\left(\mathrm{Q}\right)$ remained unchanged, when treated with ${\mathrm{H}}_2\mathrm{S}$ in a dilute mineral acid medium. However, it gave a precipitate $\left(\mathrm{R}\right)$ with ammonium chloride and ammonium hydroxide. The precipitate $\left(\mathrm{R}\right)$ gave a coloured solution $\left(\mathrm{S}\right)$ When treated with ${\mathrm{H}}_2{\mathrm{O}}_2$ in an aqueous $\mathrm{NaOH}$. The cation in precipitate $\left(\mathrm{P}\right)$ and coloured solution $\left(\mathrm{S}\right)$ contains respectively
