What do metallic electrodes measure?

• They measure E created by redox reaction on the metal surface of an electrode.

• They measure E created by acidic reaction on the metal surface of an electrode.

• They measure E created by basic reaction on the metal surface of an electrode

Which is the calculation equation of

E cell?

• E cell = E ind – E ref – E j

• E cell = E ind + E ref + E j

• E cell = E ind – E ref + E j

• E cell = E ind + E ref – E j
