2F of electricity can decompose --------------- moles of acidulated water

$$\begin{gathered} 2{\mathrm{H}}_2\mathrm{O} \stackrel{4\mathrm{F}}{\to } 2{\mathrm{H}}_2+{\mathrm{O}}_2; \\ 4 \mathrm{grams} \mathrm{of} \mathrm{hydrogen}(\hspace{0.17em}4 \mathrm{geq}) \mathrm{and} 32 \mathrm{grams} \mathrm{of} \mathrm{oxygen}( 4 \mathrm{geq}) \mathrm{are} \mathrm{produced} \mathrm{which} \mathrm{require} 4\mathrm{F} \\ \mathrm{Thus} \mathrm{for} {\mathrm{H}}_2\mathrm{O} \stackrel{2\mathrm{F}}{\to } {\mathrm{H}}_2+\frac{1}{2}{\mathrm{O}}_2; \end{gathered}$$
