In the part a of the question we are assigned to the task to write the reaction occurs at the anode.
00:08
In the galvanic cell, species with more positive reduction potential will cause to the cathode and the species with more negative reduction potential or less positive reduction potential will cause to the anode.
00:35
The cell is given as chromium, chromium 3 positive, ag positive, ag.
00:44
And the reduction potential is given as chromium 3 positive to chromium is equals to minus 0 .74 volts.
00:54
And ag positive to ag is equal to plus 0 .80.
01:01
Now, the reduction potential for a .g positive to a .g is more positive.
01:08
Therefore, a .g will cause to the cathode and chromium will cause to the anode.
01:16
The reactionate anode is represented as chromium solid is converted into chromium 3 positive equals plus 3 electron.
01:29
Now, in this case, oxidation of chromium occurs.
01:34
Therefore, a not chromium to chromium 3 positive is equal to plus 0 .741.
01:43
Now, in the part b of the question, we are assigned to the task to write the reaction occurs at the cathode...
