Q21Multiple choice
Write balanced chemical equation for the following reactions: –
- (i)Permanganate ion (MnO4 ) reacts with sulphur dioxide gas in acidic medium to produce Mn2+ and hydrogensulphate ion. (Balance by ion electron method) –
- (ii)Reaction of liquid hydrazine (N2H4) with chlorate ion (ClO3 ) in basic medium produces nitric oxide gas and chloride ion in gaseous state. (Balance by oxidation number method)
- (iii)Dichlorine heptaoxide (Cl2O7) in gaseous state combines with an aqueous solution of hydrogen peroxide in acidic medium to give chlorite ion – (ClO2 ) and oxygen gas. (Balance by ion electron method)
