A certain metal M forms a soluble sulfate salt M,SO4. Suppose the left half cell of a galvanic cell apparatus is filled with a 22.5 mM solution of M,SO, and the right half cell with a 4.50 M 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. O left Which electrode will be positive? O 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.

Transcribed Image Text:A certain metal M forms a soluble sulfate salt M,SO4. Suppose the left half cell of a galvanic cell apparatus is filled with a 22.5 mM solution of M,SO,
and the right half cell with a 4.50 M 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.
O left
Which electrode will be positive?
O 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.
