17.2 Exercise 1

Write cell schematics for the following cell reactions, using platinum as an inert electrode as needed.

(a) $\text{Mg} \left(s\right) + \text{Ni}^{2+} \left(a q\right) \rightarrow \text{Mg}^{2+} \left(a q\right) + \text{Ni} \left(s\right)$

(b) $2 \text{Ag}^{+} \left(a q\right) + \text{Cu} \left(s\right) \rightarrow \text{Cu}^{2+} \left(a q\right) + \text{2Ag} \left(s\right)$

(c) $\text{Mn} \left(s\right) + \text{Sn}(\text{NO}_{3} \left.\right)_{2} \left(a q\right) \rightarrow \text{Mn}(\text{NO}_{3} \left.\right)_{2} \left(a q\right) + \text{Sn} \left(s\right)$

(d) $3 \text{CuNO}_{3} \left(a q\right) + \text{Au}(\text{NO}_{3} \left.\right)_{3} \left(a q\right) \rightarrow \text{3Cu}(\text{NO}_{3} \left.\right)_{2} \left(a q\right) + \text{Au} \left(s\right)$
