What happens when sulphur dioxide is passed through an aqueous solution of Fe(III) salt?
Advertisements
उत्तर
SO2 acts as a reducing agent when passed through an aqueous solution containing Fe(III) salt. It reduces Fe(III) to Fe(II) i.e., ferric ions to ferrous ions.
`2Fe^(3+) + SO_2 + 2H_2O -> 2Fe^(2+) + SO_4^(2-)+4h^(+)`

An amorphous solid “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 sulphide ore. This gas decolourises acidified aqueous \[\ce{KMnO4}\] solution and reduces \[\ce{Fe^{3+}}\] to \[\ce{Fe^{2+}}\]. Identify the solid “A” and the gas “B” and write the reactions involved.
