What is Alkalinity? - Alkaline Water Filter Review

All alkaline solutions or substances are basic, but not all basic substances are alkaline. Alkalinity of a solution, water for instance, is a measure of the alkaline substances dissolved in the water/the concentration of negative OH- ions and other negative ions, and therefore a measure of the water’s ability to neutralize acid.
