Show the equation you will use to calculate the volume of 1 M Cu(NO3)2 (aq) needed to prepare a set of solutions that have concentrations in the range of 1 M to 1x10-4 M in a 10-mL volumetric flask. Write the reduction half-cell reaction for the copper(II) ion. What is the standard potential for an electrochemical cell that is prepared from a copper half-cell and a zinc half-cell

Explanation:

The equation we use to calculate the volume needed to prepare other the solution that has a concentration  and volume  is:

where;

= concentration of the first solution

= volume of the first solution

= concentration of the second solution

= volume of the second solution

2) Reduction half cell reaction for the copper (II) ion is:

3)

Since the reduction potential of Cu is more; it means copper will go into reduction and zinc will undergo oxidation.

Standard Potential =

 ( since both are reduction potential)

the answer is b. dilution
