O ELECTROCHEMISTRY Understanding concentration cells 1/5 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 1.50 M solution of M₂(SO4)3 and the right half cell with a 15.0 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 35.0 °C. Which electrode will be positive? Oleft right 3 ? What voltage will the voltmeter show? Assume its positive lead is connected to the positive electrode. 0 Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits. |||
