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 3.50 M solution of M NO3 2 and the right half cell with a 35.0 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.
