Question

Fill in the blanks :
As we descend the electrochemical series containing cations, the tendency of the cations to get ________ at the cathode increases. [oxidised/reduced]

Open in App

Solution

As we know, a cation is said to be reduced when it gains an electron and oxidised when it loses an electron.
Here, as we descend the electrochemical series, tendency to lose an electron increases.
Therefore, the tendency of the cations to get reduced at the cathode increases.
