Question

The standard reduction potential of zinc and copper are -0.76 V and +0.34 V respectively. This implies that copper has tendency to get reduced.

• A. lower
• B. equal
• C. higher

Answer 1

The correct option is C higher

Standard reduction potential measures the tendency of an element to get reduced.

Higher the $E_{red}^o$value, higher the tendency to get reduced. Lower the $E_{red}^o$value or more negative the value, higher tendency to get oxidised.

Therefore, compared to zinc, copper has higher tendency to get reduced.
