Okay, so here is about to determine the equipment constant, and i already wrote down the solutions.
00:10
I will lead you through.
00:13
So first, this reaction involves a reduction, so then we can actually express it as a half reactions.
00:23
One is oxidation, one is reduction, and it involves two reduction oxidation pairs.
00:29
One is the chlorine to the chloride.
00:33
So the standard potential of the chlorine to chloride is 1 .36.
00:39
And another is a bromine, right? bromine bromide.
00:43
And the standard reduction potential of bromine is 1 .09 volts.
00:50
From the reaction, you see, it's actually chlorine that is used to oxidize bromine, bromide.
00:57
So the chlorine here would be used as a cathode.
01:02
And bromide would be used as anode, right, in the anode.
01:14
And we know the potential of the cell would be equal to the castlet minus anode.
01:19
So it's 1 .36 minus 1 .09...
