Hello students, let's discuss the question here.
00:03
In this question, the electron transfer reactions are given, and for each of the case, we have to find out the oxidation half -cell reaction and reduction half -cell reaction.
00:16
In this case, for the first case, as we can see, that chromium here it is having zero oxidation state, and bromine here is also having zero oxidation state.
00:29
Chromium, it is having plus 3 oxidation state in product and bromine is having minus 1.
00:36
That means chromium this gets oxidized while bromine it gets reduced.
00:44
So here this will be the one which will be oxidized and bromine this will be reduced.
00:55
Hence, the oxidation half cell reaction for the first one, this will be 2 cr in solid state...
