Describe the arrhenius theory
WebThe Arrhenius theory has the most specificity out of the three theories because it states that either the H + or OH – ion must be present to be labeled an acid or base; however, this is not true in other theories. Let’s move on to a more general theory that includes more compounds – the concept of a Bronsted-Lowry acid.
