Electron TransferIn an electron transfer reaction, there is an electron exchange between a donor (𝐷𝐷) and an acceptor (𝐴𝐴).
𝐷𝐷 + 𝐴𝐴 𝐷𝐷+ + 𝐴𝐴−
The exchange results in an oxidized donor (𝐷𝐷+) and a reduced acceptor (𝐴𝐴−). The donor has lost an electron and the acceptor has gained an electron.

Mixed-valent compoundsMixed-valent (MV) molecules are capable of inner-sphere electron transfer.
The electron donor and electron acceptor are the same element, a metal (not always the case)…
M − M…but they have different oxidation states.

The ExperimentThe Ferrocene compounds have already been synthesized.
You will prepare their own solution with samples for electrochemical analysis.
You will need to prepare one sample for each ferrocene compound.
You will be required to use potentiostats to run cyclic voltammetry experiments on the compounds.
