the facts :
carboxylic acid + H2O <----> H3O+ + carboxylate ion-
RCOOH + H2O <----> H3O+ + RCOO-
as for the carboxylate ion, O single bond with C need another ion to be bonded with(after it loses H) but it so happens that it just need ion which have only one (+1) charge due to the molecular formula(which there's only one O)
when O divorced with H, she became 'janda'. she couldn't make it without a husband.
why? if not she will DEFINITELY die. BUT. he, whoever the husband-to-be, must be single and available.
she's so choosey .
