This [[delocalization]] of the electron cloud means that both of the oxygen atoms are less strongly negatively charged; the positively chargedpositive proton is therefore less strongly attracted back to the carboxylate group once it has left. In contrast, an alkoxide ion, once formed, would have a strong negative charge on the oxygen atom, which would make it difficult for the proton to escape. Thus, the carboxylate ion is more stable and carboxylic acids have a lower [[pH]] than alcohols: the higher the number of protons in solution, the lower the pH.<ref>{{cite book | author= Fox, Marye Anne; Whitesell, James K. | year = 1997 | title = Organic Chemistry | edition = 2| publisher = Jones and Bartlett Publishers | location = Sudbury, Massachusetts| isbn = 0-7637-0178-5 }}</ref>
