Write balanced chemical equations for the following processes : (a) `Cl_(2)` is passed through slaked lime.
(b) `SO_(2)` gas is passed through an aqueous solution of Fe(III) salt.

Explanation

`(a) 2Ca(OH)_(2)+2Cl_(2)rarr CaCl_(2)+Ca(O C l )_(2)+2H_(2)O`
(b) ` SO_(2)+2Fe^(3+)+2H_(2)O rarr 2 Fe^(2+)+SO_(4)^(2-) + 4H^(+)`
