alkalinity

Water's buffering strength

Alkalinity is the quality of being alkaline—having a pH above 7, the opposite of acidity.

In chemistry, it measures a solution's capacity to neutralize acids.

Water treatment and aquarium keeping depend on monitoring alkalinity: The pool's alkalinity was too high.

Alkaline substances like baking soda and ammonia have a bitter taste and slippery feel.
