If $Zn/Zn^{+2}$ electrode is diluted 100 times then the change in electromotive force will be :-
AnswerClick to flip back
A
increases of 59 mV
💡 Explanation:
Using the Nernst equation: E = E_cell - (0.059/n) * log(1/[Zn+2]). Diluting 100 times increases the concentration of the denominator in the log term, making the log term more negative, which increases the overall potential by (0.059/2) * log(100) = 0.059 V = 59 mV.
