The ability of alkali metals to raise the pH when dissolved in water helps explain how the term “alkaline” has come to describe water whose pH is greater than 7. An alkaline solution simply means it has a pH greater than 7. Alkalinity, on the other hand, refers to a solution’s quantitative ability to neutralize an acid.
