<p>sir in video of standard electrode potential part2 -----there is a question on calculating the standard electrode potential so the ans of this is calculated by first examing that both the equation are in reduction potential or not and if it is not then we need to change the sign of the e*value as in 2nd eq it is given in oxidation but we need to change it reduction potenial so&nbsp; the signs of the second equation need to be reversed to calculate&nbsp; which is not done in the video it should be as follow</p> <p>Cu+/Cu= +.52v_______1 and Cu2+/Cu+=.16v_________2</p> <p>so 2 eq implies&nbsp; __ -.16 to change it into reductonal&nbsp; potential</p> <p>so ans would be cathode -anode =0.52-(-0.16)=0.52+0.16=0.68 should be the answer</p> <p>pizzzz look at this may be i would be wrong as am not sure as i read&nbsp; in the books and numerical was solved in this way anf iam not correct plzzzz clear my dought by answering this question and if right than plzzzmake change in the video ???????</p>
