A certain metal M forms a soluble sulfate salt M2SO43 . Suppose the left half cell of a galvanic cell apparatus is filled with a 3.50M solution of M2SO43 and the right half cell with a 35.0mM 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 40.0°C . 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 2 significant digits. ×10
