What can be inferred from the negative electrode potential of the oxidation half-cell Zn
to Zn+2?
Dear student,
The standard electrode potential of the zinc electrode is negative (-0.76 V). This is because zinc has a high tendency to lose an electron. When Zn is losing its electrons it becomes a Zn2+ ion. Hence, it forms an anode in the electrochemical cell because in the anode loss of electrons (i.e, oxidation) takes place. Hence, the anode is also called a negative electrode.
The reaction at the anode is as follows:
Zn ---> Zn2+ + 2 e-
