(a)
Interpretation:
The balanced oxidation-reduction equation of given
Concept Introduction:
Oxidation is defined as a loss of electrons, loss of hydrogen atoms, or gain of oxygen atoms.
Reduction is defined as a gain of electrons, gain of hydrogen atoms, or loss of oxygen atoms.
Half-reaction, one oxidation and one reduction are exactly that: one-half of a complete reaction. The two half-reactions combine to produce the complete net cell reaction.
(b)
Interpretation:
From the standard cell voltage and concentration of zinc chloride, the measured cell voltage has to be calculated.
Concept Introduction:
The relationship between cell potential and reaction quotient is given by
