In solutions of polar solvents, PCl 5 undergoes " autoionization ".
2.
For autoionization, the 3s ?! 2p transition provides the energy to remove the 3p electron.
3.
The F ", produced by autoionization of hydrogen fluoride, reacts with SbF 5 to yield the adduct.
4.
"' Autoionization "'is a process by which an atom or a molecule in an excited state ionized state.
5.
When autoionization occurs, the np ?! 2s de-excitation provides the energy needed to remove one 2p electron and form the Ne + ground state.
6.
Unless a very large potential is applied to cause an increase in the autoionization of water the electrolysis of pure water proceeds very slowly limited by the overall conductivity.

:: Several things I should add : While absolutely pure water contains equal concentrations of hydronium and hydroxide ions, the absolute concentrations of them varies slightly with temperature ( see autoionization constant for water ).
8.
:: I think the OP may be confusing things related to the autoionization of water and the implications for acid-base " 32 " 17 : 16, 15 November 2016 ( UTC)

Pure water is a fairly good insulator since it has a low autoionization, K w = 1.0?0 " 14 at room temperature and thus pure water conducts current poorly, 0.055 �S�cm " 1.
10.
The difficulty in the production of heavy Rydberg systems arises in finding an energetic pathway by which a molecule can be excited with just the right energy to form an ion pair, without sufficient internal energy to cause autodissociation ( a process analogous to autoionization in atoms ) or rapid dissociation due to collisions or local fields.
