The voltaic cell x(s) | x2+(1.0 M) || Cu2+(1.0 M) | Cu(s) was constructed and its cell potential was measured as 1.97 V. a. Which half-cell produces this cell potential?

The half-cell that produces this cell potential is reduction cell potential; x(s) | x2+(1.0 M)

Explanation:

Positive potential is associated with reduction or cathodic half reaction:

x(s) | x2+(1.0 M):

Negative potential is  associated with oxidation or Anodic half reaction:

Cu2+(1.0 M) | Cu(s): =

The given cell potential is measured as +1.97 V,

Therefore, the half-cell that produces this cell potential is reduction cell potential; x(s) | x2+(1.0 M).

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
