Strong Acids and Bases. Acids and bases that are completely ionized when dissolved in water are called strong acids and strong bases There are only a few strong acids and bases, and everyone should know their names and properties. These acids are often used in industry and everyday life. The concentrations of acids and bases are often expressed in terms of pH, and as an educated person, you should have the skill to convert concentrations into pH and pOH.
Here is a list of ten common bases with chemical structures, chemical formulas and alternate names. Note that strong and weak means the amount the base will dissociate in water into component ions. Strong bases will completely dissociate in water into their component ions. Weak bases only partially dissociate in water. Lewis bases are bases that can donate an electron pair to a Lewis acid.
