Final answer:
Strong bases that can deprotonate H2O include hydroxides of alkali metals and heavy alkaline earth metals. Strong acids such as HCl, HBr, HI, HClO4, HNO3, and H2SO4 also have the capacity to deprotonate water.
Step-by-step explanation:
Strong bases are hydroxides of alkali metals, i.e., LiOH, NaOH, KOH, RbOH, and CSOH, and hydroxides of heavy alkaline earth metals, i.e., Ca(OH)2, Sr(OH)2 and Ba(OH)2, which are strong electrolytes. Strong acids, i.e., HCl, HBr, HI, HClO4, HNO3, and H2SO4, are molecular compounds but are strong electrolytes because they dissociate almost 100% into ions when dissolved in water.
