Strength is an important quality in the use of metals. This is especially true in construction, transportation, heavy industry and tool making. Metal alloys are often stronger than a metal in their pure form. In discussing the strongest metals, we should first consider what we mean by strength.
Strong acids and strong bases are strong electrolytes [e.g., HCl(aq), H 2 SO 4 (aq), HClO 4 (aq);NaOH(aq)]. There are virtually no molecules of a strong acid or base in solution, only ions.Know the strong acids and bases on the accompanying hand-out Strong and Weak Acidsand Bases. Assume that any other acid or base you encounter in this course is weak, unlesstold to the contrary. [Note: Mg(OH) 2, an insoluble compound, is a strong base because it is anionic compound and therefore a strong electrolyte.].
