13.106 A piece of magnesium ribbon and a copper wire are partially immersed in a 0.1 M HCI solution in a beaker. The metals are joined externally by another piece of metal wire. Bubbles are seen to evolve at both the Mg and Cu surfaces. (a) Write equations representing the reactions occurring at the metals. (b) What visual evidence would you seek to show that Cu is not oxidized to Cu2+? (c) At some stage, NaOH solution is added to the beaker to neutralize the HCI. Upon further addition of NaOH, a white precipitate forms. What is it?
