Question

Identify the oxidation numbers for all the elements in the reactants and products for 2mno4−(aq)+3s2−(aq)+4h2o(l)→3s(s)+2mno2(s)+8oh−(aq)

Answer 1

The oxidation number if eah of the elements is as follows;

• Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
• Oxidation number if hydrogen is +1 on both sides
• The oxidation number of oxygen is -2 on both sides
• The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.

What is a redox reaction?

A redox reaction is one in which there is a change in the oxidation number of the reactants from left to right.

Let us now consider the oxidation  number of each element from left to right;

• Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
• Oxidation number if hydrogen is +1 on both sides
• The oxidation number of oxygen is -2 on both sides
• The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.
