Question

The emf of a galvanic cell, with electrode potential of Zn²⁺ = - 0.76 V and that of Cu²⁺ = 0.34 V, is ______.

Options

• 0.76 V

• 1.1 V

• - 1.1 V

• 1.6 V

Answer 1

The emf of a galvanic cell, with electrode potential of Zn²⁺ = - 0.76 V and that of Cu²⁺ = 0.34 V, is 1.1 V.

Explanation:

`"E"_"cell" = "E"_"Cathode"^0 - "E"_"Anode"^0`

= 0.34 - (- 0.76) = 1.1 V
