Question

Why does $\ce{Cl-}$ discharge before $\ce{OH-}$ in NaCl solution electrolysis even though $\ce{OH-}$ is lower in the series?

Accepted Answer

because of much higher molarity of $\ce{Cl-}$

Answer

because of nature of electrode only

Answer

because $\ce{Cl-}$ is heavier

Answer

because $\ce{Cl-}$ is positive

Why does ClX−\ce{Cl-}ClX− discharge before OHX−\ce{OH-}OHX− in NaCl solution electrolysis even though OHX−\ce{OH-}OHX− is lower in the series?
