What is the standard reduction potential for the half-reaction Li = Li+ + e- ?
To determine the standard reduction potential (E°) for the half-reaction Li = Li+ + e-, we can refer to the Standard Reduction Potential Table. This table provides a list of standard reduction potentials for various half-reactions.
The standard reduction potential is a measure of the tendency of a species to gain electrons and be reduced. It is given in volts (V) and is typically referenced to the hydrogen half-reaction (H+ + e- = 1/2 H2).
To find the standard reduction potential for the Li half-reaction, locate the entry for lithium (Li) in the Standard Reduction Potential Table. The standard reduction potential for the Li+ + e- = Li half-reaction is -3.040 V.
Keep in mind that the standard reduction potential values in the table are for the reduction half-reaction, which means they are reversed if you are interested in the oxidation half-reaction.
