Vedclass · Answer

(C) During the electrolysis of water, $H_{2}O$ molecules are decomposed into $H_{2}$ and $O_{2}$ gas more readily than $D_{2}O$ molecules due to the kinetic isotope effect. As a result, the concentration of heavy water $(D_{2}O)$ in the remaining liquid increases over time. Since the density of $D_{2}O$ $(1.107 \ g/cm^3)$ is higher than that of $H_{2}O$ $(1.00 \ g/cm^3)$, the overall density of the remaining liquid water increases.
