Solution

The correct option is C both (A) and (B)
Lead often appears more noble (unreactive) than expected from its standard patential of $- 0.13 V$ . This inertness is partly due to the surface coating of oxide and partly due to the high over potential for reduction of $H^{+}$ to $H_{2}$ at Pb surface.

Electrochemical series is a series of elements arranged in increasing order of their reduction potential and $E_{H^{+} / H_{2}}^{0} = 0$ . The metals above $H_{2}$ have – ve reduction potential, they are more reactive than hydrogen whereas metals below hydrogen are less reactive than $H_{2}$ . Reduction potential of metal depends upon

Which of the following is best reducing agent?

Q. If for an electrode, the standard reduction potential is negative then, it is a ________ than hydrogen electrode.

Assertion: The more negative is the standard reduction potential, greater is its ability to displace H

from acid.

Reason: Strength of reducing agent increases with the increase in the negative value of the standard reduction potential.
