Question

When the following oxidation-reduction in basic solutions is balanced, which is the lowest whole number coefficient for OH^-, and on which of the balanced equation should it appear? A strip of iron in a 1 M solution of iron(II) surface, and a strip of copper is placed in a 2 M solution of copper(II) chloride. The two solutions are connected with a salt bridge, and the two bridge, and the two metals are connected to a voltmeter. With the two electrodes connected together, how do the Cl- ions move?

Explanation / Answer

24. In the balanced equation, the coefficient of OH- is,

B) 2, reactant side

25. The movement of Cl- in the cell would be,

D) In the direction opposite to the movement of sulfate ion

26. The cell potential and reducing agent here are,

C) 2.05 V and Pb
