How to measure the pH value?

First, test the pH value of your  tap water

Take some tap water into a small glass, add two to four drops of the indicator fluid.  Mix the water with the testing liquid. Now compare the color with the pH color chart. Typically, the pH of tap water at about pH 7.

 

Secondly, test the pH of your alkaline water

Take a second glass and fill it with a little bit of alkaline water. Again, add two to four drops of the indicator liquid and mix it with the alkaline water. Now compare this color with the pH color chart.
