When MnO₂is fused with KOH , a purple green colored compound is formed.
see the reaction :-
2MnO₂ + 4KOH + O₂ ------> 2K₂MnO₄( purple green) + 2H₂O
When 2 moles of MnO₂ is fused with 4 moles of KOH , 2 moles of purple green compound K₂mnO₄ and 2 moles of water are formed.
Hence, answer is K₂MnO₄ (purple green)
