A student sets up a voltaic cell using a 1 M zinc sulfate solution with a zinc electrode and a 1 M tin(1I) nitrate solution with a tin electrode, connecting the two cells with a salt bridge. The student connects the red lead to the zinc electrode and the black lead to the tin electrode. The voltmeter reads a voltage of -0.62 V. -0.62 Zn Sn 1M 1M Zn2+ Sn2+ Based on the student's experimental setup and voltage measurement, which of these statements is true? Select the single best answer. A. The identity of the metal electrodes should not match the aqueous metal ion in each solution. B. The leads are not connected correctly. C. The salt bridge causes the voltage to be negative. D. The voltage difference between zinc and tin should be 0.00 volts.
