While technically a weak acid, hydrofluoric acid is extremely powerful and highly corrosive. Strong Acids Strong acids dissociate completely into their ions in water, yielding one or more protons (hydrogen cations ) per molecule. WebThey essentially act as diprotic acids with two different equivalence points. One equivalence point below 7 and one above seven for the amino acid alanine for example. Typically, the conjugate base that is formed from the FIRST dissociation of a polyprotic acid is still considered a weak acid itself and will undergo acid hydrolysis with water. dream boy tickets
