WebIdentify each acid or base as strong or weak. HCl; Mg(OH) 2 C 5 H 5 N; Solution. Because HCl is listed in Table 12.1, it is a strong acid. Because Mg(OH) 2 is listed in Table 12.1, it is a strong base. The nitrogen in C 5 H 5 N would act as a proton acceptor and therefore can be considered a base, but because it does not contain an OH compound, it cannot be … WebA weak acid is, by definition, an acid that dissociates incompletely in water. The degree of dissociation is an important characteristic of weak acids. A stronger weak acid will have a higher degree of dissociation than a weaker weak acid.

WebWeak acids. Explaining the term "weak acid" A weak acid is one which doesn't ionise fully when it is dissolved in water. Ethanoic acid is a typical weak acid. It reacts with water to produce hydroxonium ions and ethanoate ions, but the back reaction is more successful than the forward one. The ions react very easily to reform the acid and the ...
