An aqueous compound of an inorganic compound (X) shows the following reactions: a. it decolourises and acidified KMnO_(4) solution accompanied by the evolution of oxygen. b. it liberates I_(2) from an acidified KI solution. c. It gives a brown precipitate with alkaline KMnO_(4) solution with evolution of oxygen. d. It removes black stains from old oil paintings. Identify (X) and give chemical equtions for the reaction at steps (a) to (d).

Name the gas that can readily decolourise acidified KMnO_(4) solution:

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.

Name the gas that decolourises acidified KMnO_4 solution.

A natural compound (A) (C_(7)H_(6)O) forms an oxime. When (A) is treated with acetic anhydride and sodium acetate, it yields a product (B) which decolourises alkaline KMnO_(4) solution and also gives effervscence with NaHCO_(3) . Explain the reaction and assign structures to (A) and (B).

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

When hydrogen gas is bubbled through acidified KMnO_(4) , colour is not discharged. The colour of the acidified KMnO_(4) solution can be discharged by

Account for the following : a) Moist SO_(2) decolourises KMnO_(4) solution. b) In general interhalogen compounds are more reactive than halogens (except fluorine). c) Ozone acts as a powerful oxidizing agent
