WitrynaA strong acid is an acid which is completely ionized in an aqueous solution. Hydrogen chloride (HCl) ionizes completely into hydrogen ions and chloride ions in water. A weak acid is an acid that ionizes only slightly in an aqueous solution. Acetic acid (found in vinegar) is a very common weak acid. Its ionization is shown below. WitrynaKCN is the product of the reaction of a strong base, KOH, with a weak acid, HCN. Therefore, the potassium ion will not act as an acid in aqueous solution but the cyanide ion will be a strong enough base to accept some hydrogen ions from water.
