WebNational Center for Biotechnology Information WebThe pH of 100% ethanol is 7.33, compared to 7.00 for pure water. Ethanol can be quantitatively converted to its conjugate base, the ethoxide ion (CH 3 CH 2 O−), by reaction with an alkali metal such as sodium: 2CH 3 CH 2 OH + 2Na → 2CH 3 CH 2 ONa + H 2, or a very strong base such as sodium hydride: CH 3 CH 2 OH + NaH → CH 3 CH 2 ONa + H 2 .
