PRACTICAL CHEMISTRY

37546 An aqueous solution of colourless metal sulphate \(M\), gives a white precipitate with \(NaOH\). This was soluble in excess of \(NaOH\). On passing \({H_2}S\) through this solution a white precipitate is formed. The metal \(M\) in the salt is

1 \(Ca\)
2 \(Ba\)
3 \(Al\)
4 \(Zn\)
PRACTICAL CHEMISTRY

37547 A compound is soluble in water. If ammonia is added, a red precipitate appears which is soluble in dilute \(HCl\). The compound has

1 Aluminium
2 Zinc
3 Iron
4 Cadmium
PRACTICAL CHEMISTRY

37548 Nessler's reagent is

1 \(KHg{I_4}\)
2 \({K_2}Hg{I_4} + N{H_4}OH\)
3 \({K_2}Hg{I_4} + KOH\)
4 \(KHg{I_4} + N{H_4}OH\)
