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

Sn(s)\rightarrow Sn^{2+}(aq)+2e^-

At the cathode, reduction occurs

Cu^{2+}(aq)+2e^-\rightarrow Cu(s)

E^o_{cell} =E^o_{cathode} -E^o_{anode}

        = 0.337 - (-0.140)

        = 0.477 V

Thus, The standard potential for the given galvanic cell is 0.477 V
