![Understanding concentration cells
A certain metal M forms a soluble nitrate salt MNO 3. Suppose the left half cell of a galvanic cell apparatus is filled with a 3.50 M solution of
MNO3 and the right half cell with a 17.5 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 25.0 °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.
