What happens when sulphur dioxide is passed through an aqueous solution of Fe(III) salt ? |
|
Answer» Solution :`SO_(2)` acts as a reducing agent and hence REDUCES an AQUEOUS solution of Fe(III) salt to Fe(II) salt. `{:(SO_(2)+ 2H_(2)O rarr SO_(4)^(2-) + 4H^(+) + 2e^(-)),(2 Fe^(3+)+2 e^(-) rarr 2 Fe^(2+)),(bar(2Fe^(3+)+SO_(2)2H(2)O rarr 2 Fe^(2+)+SO_(4)^(2-)+4H^(+))):}` |
