Question
A certain metal M forms a soluble sulfate salt M₂(SO4)3. Suppose the left half cell of a galvanic cell apparatus is filled
a 300. mM solution of M₂(SO4), and the right half cell with a 3.00 M solution of the same substance. Electrodes mad
M are dipped into both solutions and a voltmeter is connected between them. The temperature of the apparatus is held
constant at 20.0 °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.
