NaOH Ba (OH)2 An acid can be defined as a substance that loses one or more H+ ions when dissolved in water. An H+ ion is a hydrogen atom that has lost a (n) and is therefore just a (n) .
WebSo, a strong base can be defined as a base that can deprotonate a very weak acid. In other words, a strong base has a pKb < 0. So, in summary: Strong acid: pKa < 0 or -1.74 (as mentioned above) Strong base: pKb < 0 Almost strong acid: pKa between 0 and -1.74 (this is not accepted by all sources) Weak acid: pKa > 0 Weak base: pKb > 0 WebHistorically, the first chemical definition of an acid and a base was put forward by Svante Arrhenius, a Swedish chemist, in 1884. An Arrhenius acid is a compound that increases the H + ion concentration in aqueous solution .
