Problem Page

A certain metal

M

forms a soluble sulfate salt

M2SO4

. Suppose the left half cell of a galvanic cell apparatus is filled with a

3.00mM

solution of

M2SO4

and the right half cell with a

3.00M

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

30.0°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.
