Question

Which element is reduced in this reaction? 2kmno4 3na2so3 h2o→2mno2 3na2so4 2koh

Answer 1

In a redox chemical reaction, one species gets reduced and another gets oxidized. Manganese element is reduced in this reaction.

What is oxidized and reduced?

In a redox reaction, the increase or decrease in the oxidation number and electrons results in the reduction and oxidation of the chemical species. The oxidation and reduction occur simultaneously in a reaction.

The oxidation number of Mn in permanganate ion was +8 on the left side and decreased to +4 on the right side of the equation. Potassium permanganate is an oxidizing agent that has reduced the manganese ion of the permanganate ion.

Therefore, manganese is reduced.
