Question 5 options: The cell potential for an electrochemical cell with a Zn, Zn2 half-cell and an Al, Al3 half-cell is _____ V.
Mashcka [7]

Answer:

The voltage is  E_{cell} =  0.944 \ V

Explanation:

Generally the half reaction for Zn, Zn2 half-cell is mathematically represented as

    Zn_{(s)}   ⇔   Zn^{2+}_{ (aq)} + 2e^-    (reference study academy)

and the electric potential for this is a constant value

     E_{zn } =  -0.7618 \ V

Generally the half reaction for Al, Al3 half-cell is mathematically represented as

      Al^{3+}  _{(aq)} + 3e^-  ⇔  Al_{(s)}

and the electric potential for this is constant value  

       E_{Al  } =  -1.662 \ V

Therefore the cell potential for an electrochemical cell  is mathematically represented as

          E_{cell} =  E_{zn }  -  E_{Al }

substituting values

         E_{cell} =  -0.718  - (-1.662)

        E_{cell} =  0.944 \ V
