Some amines are considered strong bases
WebWhat is the weakest base? Water can be considered both a weak acid and a weak base, because it ionizes slightly to give both hydrogen ions and hydroxide ions. It is definitely one of the weakest bases! Salts of strong acids and strong bases create solutions are considered neutral. Examples are sodium perchlorate, sodium chloride, and sodium ... WebAmines react with acids to accept a hydrogen ion, making them an acid according to the Bronsted-Lowry definition. This gives the amine a positive charge. Amines can accept a …
