Antimony Sulphide (Sb_(2)S_(3)) reacts with sulphuric acid (H_(2)SO_(4)) to form Antimonic (H_(3)SbO_(4)) and sulphur dioxide (SO_(2)). What are the coefficients of H_(2)SO_(4),H_(3)SbO_(4),SO_(2) respectively in the balanced redox reaction.

Answer»

`11,2,11`
`2,4,4`
`2,2,11`
`11,2,14`

Solution :REACTION : `Sb_(2)S_(3)+H_(2)SO_(4)toH_(3)SbO_(4)+SO_(2)`
(i) Oxidation PART :

(ii) Reduction part :

Reduction `xx11:=11H_(2)SO_(4)to11SO_(2)" "...(R)`
(III) REDOX :
(O) + (R) = Redox
`Sb_(2)S_(3)+11H_(2)SO_(4)to2H_(3)SbO_(4)+14SO_(2)` ... Redox
(iv) Balancing O and H by `H_(2)O` :
`Sb_(2)S_(3)+11H_(2)SO_(4)to2H_(3)SbO_(4)+14SO_(2)+8H_(2)O`
(v) Coefficient of `H_(2)SO_(4)` = 11
Coefficient of `H_(3)SbO_(4)` = 2
Coefficient of `SO_(2)` = 14
