A violetcomopund of manganese (A) decomposes on heating to liberate oxygen and compounds (B) and (C )of manganese are formed. Compounds (C ) reacts with KOH in the presence of potassium nitrate to give compound (B). On heating compound(C ) with conc. H_(2) SO_(4) and NaCl, chlorine gas is liberated and a compound (D) of manganesealong with other products is formed. Identify compounds A to Dand also explain the reactions involved. |

Answer» SOLUTION :`A=KMnO_(4) , B=K_(2)MnO_(4), C = MnO_(2), D = MnCl_(2)` Reaction `: underset((A))(2KMnO_(4))overset(Delta)(RARR)underset((B))(K_(2)MnO_(4))+underset((C ))(MnO_(2))+O_(2)` `2MnO_(2)+4KOH +O_(2)rarr2K_(2)MnO_(4)+2H_(2)O` `MnO_(2)+ 4NaCl+ 4H_(2)SO_(4) rarr underset((D))(MnCl_(2))+2NaHSO_(4)+2H_(2)O+ Cl_(2)` |
