What is alkaline water?
Alkaline water is water that contains alkali minerals (alkaline) which produce hydroxide ions when they are dissolved in the water. The hydroxide ions make the pH level of water higher than 7 by reducing the hydrogen ion molar concentration in water to lower than 10-7((-log(H+))<10-7M).
Water is a combination of hydrogen (H+) and hydroxide (OH-) ions which form the H2O formula. The number of (H+) and (OH-) ions are equal in pure water (neutral).
Alkaline water falls in the basic category because it has a lower hydrogen ion concentration and a pH greater than 7.
But, what is actually alkaline?
Alkaline only comes from alkali minerals when they are dissolved in the water to produce hydroxide ions (OH-)
Alkali refers to ionic compounds that contain alkali metals such as sodium (Na), potassium (K), lithium (Li), rubidium (Rb), cesium (Cs), and francium (Fr) which form hydroxide ions (OH-) when dissolved in water. It reduces hydrogen ions (H+) concentration and raises the pH of water.
If there are no hydroxide ions (OH-) created in the water, then it’s not alkaline. If there are OH- ions created, but the hydrogen ion molar concentration is not lower than 10-7, then the water is also not alkaline.
