All the others are weak acids. A strong acid is one that dissociates completely when it dissolves in water. Dissociate means that the substance splits apart into ions. There are only a few strong acids in water, they are: HBr, HCl, HI, HNO3, HClO4 and H2SO4 (for the first H only) All other acids are weak acids. Chemists use the term strong or weak with regard to acids and bases to tell how much the substance dissociates in water.
A strong base is a basic chemical compound that can remove a proton (H+) from (or deprotonate) a molecule of a very weak acid in an acid-base reaction. 1  Common examples of strong bases include hydroxides of alkali metals and alkaline earth metals like NaOH and Ca(OH) 2 respectively.
