1 atm pressure of H2 would be required to make emf of the hydrogen electrode zero in water at 25°C.

Q. What pressure of $H_{2}$ would be required to make emf of the hydrogen electrode zero in water at $2 5^{\circ} C$ ?

$1 0^{- 7} a t m$

$1 0^{- 14} a t m$

$1 a t m$

$0.5 a t m$

$1$ atm pressure of $H_{2}$ would be required to make emf of the hydrogen electrode zero in water at $2 5^{\circ} C$ .
