Hello everyone, let's look at the question.
00:04
Now in this question we have given the four species and we have to arrange these species according to their ability to act as an oxidizing agent.
00:13
So we have to arrange them like the one which is best oxidizing agent and then as a poor oxidizing agent.
00:20
See here the given species are nickel 2 plus calcium 2 plus, ag plus and it is chromium 3 plus.
00:36
Now in order to compare their oxidizing power, see here, the molecule which can easily undergo reduction will oxidize the other.
00:46
Okay, see, oxidizing agent is the one which oxidizes the other and itself undergoes reduction.
00:53
So that means what? so the best oxidizing agent will be the one which can easily undergo reduction, right? see, to compare their what oxidizing power, first we should compare their reduction potential.
01:05
The one which is having more reduction potential can undergo easy, the ease of reduction so that it can undergo a better oxidizing agent.
01:17
So if i compare the reduction potential of these, so the nickel 2 plus nickel is having a reduction potential of minus 0 .23 volt.
01:33
Calcium 2 plus is having a reduction potential of minus 2 .87 volt and the reduction potential of ag plus is plus 0 .80 and the reduction potential of chromium 3 plus is a .0 is 0 .74 volt.
02:12
So this is minus...
