Name the gas that decolourises acidified KMnO_4 solution.

White crystal (A) on treatment with AgNO_(3) gives white crystalline precipitate. (A) discharges the colour of KMnO_(4) solution but no gas is evolved. Probable radical present in (A) is:

Magnesium on heating in air gives (A) and (B) . On reaction with water (B) gives a colourless gas (C ).(C ) when passed through CuSO_(4) solution, gives a blue coloured solution (D) . Identify (C ) and (D) .

An amorphous soild A burns in air to form a gas B which turns lime water milky. The gas is also produced as a by - product during roasting of sulohide ore. This gas decolourises acidified aqueous KMnO_(4) solution and reduces Fe^(3+) to Fe^(2+) . Identify the solid A and the gas B and write the reactions involved.

When hypo solution is added to KMnO_(4) solution then

A metal (A) on heating in nitrogen gas given compound B.B on treatment with H_(2)O givens a colourless gas which when passed throught CuSO_(4) solution given a dark blue - violet coloured solution . A and B respectivley are :

A metal (A) on heating in nitrogen gas given compound B.B on teratement with H_(2)O givens a colourless gas which when passed throught CuSO_(4) solution given a dark blue - violet coloured solution . A and B respectivley are :
