Hi, in this question we are asked to find out the substance which is oxidized and which is reduced and what is a reducing agent and oxidizing agent.
00:09
So the reaction given here is fe2 plus in the aquaise state reacted with sn4 plus in the aquaic state.
00:18
So this gives fe3 plus in the aquaise state along with sn2 plus in the aquis state.
00:26
Now before moving into the question, let us understand some concepts.
00:32
So oxidation, when there is an increase in oxidation number, it is oxidation.
00:38
When there is an increase in oxidation number, then it is oxidation, then reduction.
00:53
Reduction is basically when there is a decrease in oxidation number.
00:58
When there is a decrease in oxidation number.
01:10
Now oxidizing agent, these are the agent that oxidizes others but itself it gets reduced.
01:23
So it oxidizes others but itself it get reduced.
01:36
Similarly for the reducing agent it reduces others.
01:48
But itself it get oxidized.
01:56
So now let's see the reaction here...
