Question

when MnO2 is fused with KOH and KNO2 a colored compound is formed. which is the compound and colour?​

Answer 1

Answer:

When MnO₂is fused with KOH , a purple green colored compound is formed.

Explanation:

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 (purplish green)
