PH and POH Calculator


About PH and POH Calculator (Formula)

pH and pOH are both measurements of acidity or basicity in a solution. The pH scale ranges from 0 to 14, with 7 being neutral. The pOH scale ranges from 0 to 14 as well, but with 7 also being neutral.

The relationship between pH and pOH can be found using the formula:

pH + pOH = 14

pH  = 14 – pOH

pOH = 14 – pH

This formula means that if you know one of the values (pH or pOH), you can find the other by subtracting it from 14. For example, if you know the pH of a solution is 4, you can use the formula above to find the pOH: pH + pOH = 14 4 + pOH = 14 pOH = 10

When you have pH and pOH, you can also find the concentration of hydrogen ions and hydroxide ions in the solution respectively.

pH = -log[H+] and pOH = -log[OH-]

Understanding the pH and pOH values can be important in fields such as chemistry, biology, and environmental science.
