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).

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
