Donor-acceptor principle
The donor-acceptor principle (also: donor-acceptor principle) is found in chemical reactions in which a particle is transferred from one reaction partner (donor) to the other reaction partner (acceptor).
Examples
An example of the donor-acceptor principle (transfer of positively charged particles) is the acid / base reaction. Here the acid is the donor, it gives off a proton to the base.
An example of the transfer of electrons is the redox reaction , in which an electron is transferred from the reducing agent (donor) to the oxidizing agent (acceptor). The lead accumulator is a practical application: An elementary lead atom (electron donor) releases two electrons under oxidation to a 4-valent lead ion , which is reduced by the electron uptake . Two divalent lead ions are formed, and the current flow in this reversible reaction supplies electrical energy .
