(X) is very important laboratory reagent which is prepared by its naturally occurring ore which is called pyrolusite. Pyrolusite when fused with alkali in the presence of O_(2), green compound (Y) is produced. (Y) is converted into (X) by electrolysis or by using ozone. Q. On small scale (X) is prepared by disproportionation of (Y) is acidic solution. which of the following is produced by disproportionation of (Y) in slightly alkaline solution.
