Question

a. What is the cell notation of the set-up?

b. What is the standard cell potential?

Tanjiro, a Chem 17.1 student, found a prehistoric katana during his trip to Japan. He inspected the katana and realized that it was made out of gold. Upon closer inspection, Tanjiro noticed that it had a lot of chips and scratches, signifying that it had been used in battle long ago. Wanting to restore the katana to its original state, Tanjiro used his knowledge in Chem 17.1 to electroplate gold into the surface of the katana using an ore his father found on their backyard. Tanjiro proceeded with the electroplating process, however, he realized that the concentration of the gold ions present in the solution is unknown, making the electroplating process difficult to plan. He then decided to use a galvanic cell to obtain the gold ion concentration. He used the half-cell reactions below: Au³+ (aq) + 3e →→ Au(s) Ni²+ *(aq) + 2e → Ni(s) E° = +1.520V E° = -0.230V Given: [Ni²+] = 0.050 M FMAU = 196.97 g/mol FMNi = 58.69 g/mol
