What is the voltage of a galvanic cell made with zinc (zn) and aluminum (al)?

Answer : The voltage of galvanic cell made with zinc and aluminum is, 0.90V

Explanation :

We are taking the value of standard reduction potential form the standard table.

In this cell, the component that has lower standard reduction potential gets oxidized and that is added to the anode compartment. The second forms the cathode compartment.

The half oxidation-reduction reaction will be :

Oxidation :      

Reduction :      

The expression for standard cell is,

Therefore, the voltage of galvanic cell made with zinc and aluminum is, 0.90 V

let that person have a turn to speak : )
