12 g of impure cyanogen undergoes hydrolysis by two different paths.
i. (CN)2+4H2O→(NH4)2C2O4
ii. (CN)2+2H2O→NH2CONH2
When 11.52 g of pure ammonium carbonate [(NH4)2CO3] was heated, the exact amount of urea was obtained. 20 mL of 1.6 M acidic KMnO4 is required to completely oxidise.
The percentage progress of the reaction in path (ii) is:
