Question

Standard electrode potential is measured taking the concentrations of all the species involved in a half-cell is ____________.

Options

• 2 M

• 4 M

• 3 M

• 1 M

Answer 1

Standard electrode potential is measured taking the concentrations of all the species involved in a half-cell is 1 M.

Explanation:

Under the standard condition that is at 298 K, the molar concentration of every species taken in each half cell is 1 M and if gases are involved the partial pressure of the gas is taken as 1 atm.
