If the measured cell potential (Ecell) is 1.800V, what is the concentration of Au³+?After determining the gold ion concentration, Tanjiro then proceeded with theelectrolysis process. He electroplated the katana using 250.0 mL of the gold solutionwith a current of 3.20A.D. How long (in hrs) will it take to electroplate the katana assuming that all gold ions areconverted to solid gold?E. What is the mass of the electroplated gold? 3.Tanjiro, a Chem 17.1 student, found a prehistoric katana during his trip toJapan. He inspected the katana and realized that it was made out of gold. Upon closerinspection, Tanjiro noticed that it had a lot of chips and scratches, signifying that it hadbeen used in battle long ago. Wanting to restore the katana to its original state, Tanjiroused his knowledge in Chem 17.1 to electroplate gold into the surface of the katana usingan ore his father found on their backyard. Tanjiro proceeded with the electroplatingprocess, however, he realized that the concentration of the gold ions present in thesolution is unknown, making the electroplating process difficult to plan. He then decidedto use a galvanic cell to obtain the gold ion concentration. He used the half-cell reactionsbelow:Au³+ (aq) + 3e → Au(s)E° = +1.520VE° = -0.230VNi²+ (aq) + 2e → Ni(s)Given:[Ni²+] = 0.050 MFMNI = 58.69 g/molFMAU = 196.97 g/mol
