2 A certain metal M forms a soluble nitrate salt M (NO3)₂. Suppose the left half cell of a galvanic cell apparatus is filled with a 5.00 M solution of M(NO3), and the right half cell with a 50.0 mM solution of the same substance. Electrodes made of M are dipped into both solutions and a voltmeter is connected between them. The temperature of the apparatus is held constant at 35.0 °C. Which electrode will be positive? What voltage will the voltmeter show? Assume its positive lead is connected to the positive electrode.
