A galvanic cell with a measured standard cell potential of 0.27 V is constructed using two beakers connected by a salt bridge. One beaker contains a strip of gallium metal immersed in a 1 M solution of GaCl,, and the other contains a piece of nickel immersed in a 1 M solution of NiC2. The half- reactions that occur when the compartments are connected are as follows: Ni2+ * (aq) + 2e¯ → Nics) Cathode: Anode: Ga(s) → Ga* (aq) + 3e- If the potential for the oxidation of Ga to Ga is 0.55 V under standard conditions, what is the potential for the oxidation of Ni to Ni2?
