![Understanding concentration cells
A certain metal M forms a soluble sulfate salt M2(SO4)3. Suppose the left half cell of a galvanic cell apparatus is filled with a 4.00 M solution of M2(SO4), and
3
the right half cell with a 400. 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 40.0 °C.
Which electrode will be positive?
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.
