Question

calculate standard EMF of a galvanic cell whose electrode potential are 0.36v and 0.42v​

Answer 1

Given:

The electrode potentials of a galvanic cell are 0.36 v and 0.42 v.

To find: ​

Calculate the standard EMF of a galvanic cell.

Solution:

The standard EMF of a galvanic cell is given by the following formula,

E₀ cell = E₀ reduction + E₀ oxidation

E₀ cell = 0.36 v + 0.42 v

∴ E₀ cell = 0.78 v
