The galvanic cell illustrated above was constructed using a salt bridge containing KNO3. A second cell is constructed from identical half-cells but uses NaNO, for the salt bridge. Which of the following best explains whether the initial potential of the second cell will be different from the initial potential of the first cell? A The initial potential of the second cell will be lower than the initial potential of the first cell because Na has a lower molar mass than K has. The initial potential of the second cell will be higher than the initial potential of the first cell because Na is less electronegative than K is. The initial potential of the second cell will be the same as the first cell because the ions from the salt bridge are not oxidized or reduced during cell operation. The initial potential of the second cell will be the same as the first cell because the standard reduction potentials of Group 1 metals are very similar.
