A certain metal forms a soluble nitrate salt . Suppose the left half cell of a galvanic cell apparatus is filled with a solution of and the right half cell with a solution of the same substance. Electrodes made of are dipped into both solutions and a voltmeter is connected between them. The temperature of the apparatus is held constant at . Which electrode will be positive? left right What voltage will the voltmeter show? Assume its positive lead is connected to the positive electrode. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.
