Ph Value Of Drinking Water

About  Ph Value Of Drinking Water

When the hydrogen ion concentration is 1 mol/L or more, the pH is not used to indicate acidity and alkalinity, but is directly expressed by the concentration of hydrogen ions. The pH of distilled water

The solution has a unique property at a specific temperature: c(H+)*c(OH-)=constant.

This constant is called the ion product constant. Usually 25 = 1*10^(-14) at 25 degrees C. The distilled water is weakly ionized into H+ and OH-, and c(H+)=c(OH-), so there is c(H+). =c(OH-)=1*10^(-7). pH value

-lg(c(H+)), which gives a theoretical value of 7.0 at 25 degrees Celsius.
