b) A 1M solutions of Cu(NO3)2 is placed in a beaker with a strip of Cu metal while a 1M solution of SrSO4 is placed in the second beaker with a strip of Sr metal. The two beakers are connected by a salt bridge, and the two metal electrodes are linked by wires to a voltmeter at 25C. i) Write the half-cell reaction occurs at anode and cathode. ii) Calculate the standard cell potential under standard conditions.
