This calculator allows you to instantly convert pH to pOH or vice versa using the following relationships:
- $$ \text{pH} + \text{pOH} = 14 $$
- $$ \text{pH} = 14 – \text{pOH} $$
- $$ \text{pOH} = 14 – \text{pH} $$
Simply enter a known pH or pOH value, and the calculator will handle the rest, providing an accurate result for determining your solution’s acidity or basicity.

Importance of pH and pOH in Chemistry
pH and pOH values are essential metrics for analyzing chemical solutions, providing insights into a solution’s acidity or basicity:
pH
pH measures the concentration of hydrogen ions (H⁺) in a solution, indicating how acidic it is. A low pH suggests a highly acidic solution, while a high pH points to a basic one. pH is fundamental in fields like biochemistry, environmental science, medicine, and industrial chemistry, where the level of acidity can influence reactions and biological processes.
pOH
pOH reflects the concentration of hydroxide ions (OH⁻) in a solution, with lower pOH values indicating higher alkalinity. Understanding pOH is equally important in applications where alkalinity impacts chemical behavior and environmental health.
By converting pH to pOH or vice versa, this calculator simplifies your ability to analyze and adjust solutions with precision—whether for laboratory experiments, quality control, or environmental testing.
pH and pOH Range
Both pH and pOH values typically range from 0 to 14 for aqueous solutions at standard temperature (25°C):
pH Range
pH values range from 0 to 14:
- 0: Extremely acidic, indicating a high concentration of H⁺ ions.
- 7: Neutral, as seen in pure water.
- 14: Highly basic, indicating a low concentration of H⁺ ions.
pOH Range
pOH values also range from 0 to 14, inversely related to pH:
- 0: Highly basic, indicating a high concentration of OH⁻ ions.
- 7: Neutral.
- 14: Very acidic, indicating a low concentration of OH⁻ ions.
With this calculator, quickly obtain accurate pH or pOH values, making it easy to evaluate and adjust solutions for precise control over their chemical properties.
