An amorphous solidA burnsin airto form a gas B whichturns limewatermilky. Thegasis also producedduringroasting of sulphide ore. This gasdecolourises acidifedaqueousKMnO_(4) solutionand reduces Fe^(3+) to Fe^(2+). Identify the solid 'A' and thegas B and write thereactionsinvolved . |

Answer» Solution :`A to S_(8) , B to SO_(2) , S_(8) + 8O_(2) OVERSET(Delta)to 8SO_(2)` `underset("(VIOLET)")(2MnO_(4)^(-)) + 5SO_(2) + 2H_(2)O to5SO_(4)^(2-) +4H^(+) + underset("(colouless)")(2Mn^(2+))` `2Fe^(3+) + SO_(2) + 2H_(2)Oto 2Fe^(2+) + SO_(4)^(2-) + 4H^(+)` |
