A certain metal M forms a soluble nitrate salt t M(NO3)². Suppose the left half cell of a galvanic cell apparatus is filled with a 2.50 M solution of M(NO3)² and the right half cell with a 125. 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? 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. ● left O right 0 X

Transcribed Image Text:A certain metal M forms a soluble nitrate salt M(NO3)3. Suppose the left half cell of a galvanic cell apparatus is filled with a 2.50 M solution of M(NO3)3 and
the right half cell with a 125. 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?
What voltage will the voltmeter show? Assume its positive lead is connected to the
positive electrode.
