An electrolytic cell similar to the one represented in Figure 1 can be used to plate
Chapter 16, Problem 110P(choose chapter or problem)
An electrolytic cell similar to the one represented in Figure \(16.17\) can be used to plate gold onto other metal surfaces. The plating reaction is: \(\mathrm{Au}^{+}(a q)+\mathrm{e}^{-} \longrightarrow \mathrm{Au}(s)\). Notice from the reaction that 1 mol \(e^{-}\) plates out 1 mol Au(s). Use this stoichiometric relationship to determine how much time is required with an electrical current of 0.200 amp to plate out \(0.400 g Au\). The amp is a unit of electrical current equivalent to 1 C/s. (Hint: Recall that the charge of an electron is \(1.60 \times 10^{-19}\) C.)
