Is any water with high pH good?
The higher the pH the more OH- ions in the water. However, it is dangerous to conclude that any water with a high pH is good. I can add potassium cyanide into water to raise the pH, but that water would obviously be fatal. High pH water, obtained from ‘drinkable’ water by filtering out pollutants and removing acid minerals and enhancing alkaline minerals that were in the original water, is good. Not just any high pH water.
