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

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

$E_{cell} = 0.944 \ V$
