Statement I: On dilution of the solution the electrode potential increases
Statement II: The effect of dilution on electrode potential depends on the electrode whether it is metal or non-metal
Answer & explanation
Correct answer: option 1
The answer is (4) Statement I is false but Statement II is correct.
Statement I is false because the electrode potential decreases on dilution of the solution. This is because the concentration of the ions in the solution decreases, which makes it more difficult for the electrons to be transferred from the electrode to the ions.
Statement II is correct because the effect of dilution on electrode potential depends on the type of electrode. For a metal electrode, the electrode potential decreases on dilution, while for a non-metal electrode, the electrode potential increases on dilution.
