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.

Nitrogen dioxide is mostly soluble in the ,alkaline solution,, while the NO is not and would come out of ,solution, as a gas and enter the air, where it would react with oxygen and form nitrogen dioxide. One thought is to use a “weaker” ,acid,, that is, an ,acid, that does not react as vigorously with caustic, creating heat that increases the formation of nitrogen oxide gas.
