When sulphur is boiled with Na_(2)SO_(3) solution, the compound formed is

When sulphur is boiled is boiled with Na_2 SO_3 , a compound (X) is produced, (X) with excess of AgNO_3 solution gives a compound (Y) which is soluble in water and produces a black coloured sulphide (Z) . Identify compounds (X),(Y) and (Z) .

When sulphur is boiled is boiled with Na_2 SO_3 , a compound (X) is produced, (X) with excess of AgNO_3 solution gives a compound (Y) which is soluble in water and produces a black coloured sulphide (Z) . Identify compounds (X),(Y) and (Z) .

A white precipitate (X) is formed when a mineral (A) is boiled with Na_(2)CO_(3) solution. The precipitate is filtered and filtrate contains two compound (Y) and (Z). The compound (Y) is removed by crystallization and when CO_(2) is passed through the filtrate obtained after crystallization, then (Z) changed to (Y) . When compound (Y) is heated, it gives two compounds (Z) and (T). Compound (T) on heating with cobalt oxide produces blue coloured substance (S) The compound (Y) in the filtrate when (A) is boiled with Na_(2)CO_(3) is

When SO_(2) is passed into an Na_(2)CO_(3) solution, it produces

ZnSO_(4) on boiling with Na_(2)C0_(3) solution produces
