21) The following schematic of a Daniell cell illustrates the direction of electron flow as the cell discharges. Select the best description of the reactions that occur in this cell. A) $$\mathrm{Zn}$$ metal is oxidized to Zinc ions $$\left({\mathrm{Zn}}^{2+}\right)$$ at electrode a and $$\mathrm{Cu}$$ metal is oxidized to Copper ions $$(\mathrm{Cu}2+)$$ ions at electrode $$\underline{b}$$. B) Zinc ions $$\left({\mathrm{Zn}}^{2+}\right)$$ are oxidized to $$\mathrm{Zn}$$ metal at electrode a and $$\mathrm{Cu}$$ metal is reduced to Copper ions $$\left({\mathrm{Cu}}^{2+}\right)$$ ions at electrode $$\underline{b}$$. reduced to $$\mathrm{Cu}$$ metal at electrode $$\underline{\mathrm{b}.}$$ D) Zinc ions $$\left({\mathrm{Zn}}^{2+}\right)$$ are reduced to $$\mathrm{Zn}$$ metal at electrode a and Cu metal is oxidized to Copper ions $$\left({\mathrm{Cu}}^{2+}\right)$$ ions at electrode $$\underline{b}$$.
