What is the standard reduction potential for given that?
The standard reduction potential is defined relative to a standard hydrogen electrode (SHE) reference electrode, which is arbitrarily given a potential of 0.00 volts.
At what pH will hydrogen electrode at 298 K show an electrode potential of 0.118 V when hydrogen gas is bubbled at 1 atm pressure?
In which reactions is iron oxidized to Fe3+?
An oxidation/reduction reaction is one in which electrons are transferred from one reactant to another. An example is the oxidation of iron(II) ions by cerium(IV) ions: Ce4+ + Fe2+ ⇌ Ce3+ + Fe3+ Here, Ce4+ ion extracts an electron from Fe2+ to form Ce3+ and Fe3+ ions.
How is standard electrode potential measured?
Reason: Standard electrode potentials are measured using a hydrogen half-cell reference electrode whose potential is known.
