The standard potential for the given galvanic cell is 0.477 V
<h3>What is electrode potential?</h3>The electrode potential is the electromotive force of a galvanic cell built using a standard reference electrode and another electrode whose potential is to be found.
There are two types of electrode potential
Oxidation potential - The potential associated with oxidation reaction is known as oxidation potential
Reduction potential - The potential associated with reduction reaction is known as reduction potential
At the anode, oxidation occurs
At the cathode, reduction occurs
= 0.337 - (-0.140)
= 0.477 V
Thus, The standard potential for the given galvanic cell is 0.477 V
