With this pH calculator, you can determine the pH of a solution in a few ways. It can convert pH to H+, as well as calculate pH from the ionization constant and concentration. The pH value is an essential factor in chemistry, medicine, and daily life. Read the text below to find out...
Make a solution of dish detergent and soak the probe for 5 to 10 minutes. For stubborn materials gently scrub the reference junction and glass with a soft toothbrush. For difficult organic fouling a 5 percent solution of bleach can be substituted for the dish detergent. After cleaning the ...

What is the pH value of water? pH Scale: The pH scale is a scale that measures the degree of acidity or alkalinity of a solution. An acid has a pH of 1 to less than 7. An alkaline or a basic solution has a pH of more than 7 to 14 on the pH scale. ...
normal soap pH about 9-10 bleach pH about 12.5There are two things worth of remembering about the pH scale. First, as the pH scale is logarithmic 1 unit pH change means tenfold change in the H+ ion concentration. Second, while only solution with pH=7.00 is strictly neutral (see water ...
Alkaline substances include ammonia, baking powder and bleach. Diluting an alkali decreases the concentration of OH-(aq) ions, which decreases the pH level of the solution towards 7, making it less alkaline. However, the pH level of an alkaline solution cannot become lower than 7, because the...
