Which of the ions will give colourless aqueous solution?

An amorphous solid (A) burns in air to form a gas (B) which turns lime water milky . The gas is also produced as a byproduct during roasting of sulphide 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.
