Any chance a weak acid has to form, it will (the same with a weak base). As some C 2 H 3 O 2 − ions hydrolyze with H 2 O to make the molecular weak acid, OH − ions are produced. OH − ions make solutions basic. Thus NaC 2 H 3 O 2 solutions are slightly basic, so such a salt is called a basic salt. how to view my listings on marketplace
