The pH pOH H+ OH- Calculator is a powerful tool used in chemistry to determine various parameters related to the acidity and basicity of a solution. It helps users calculate the pH and pOH values, as well as the concentrations of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. By inputting the concentration of either H+ or OH-, the calculator can automatically determine the corresponding pH or pOH value, and vice versa. This tool is invaluable for scientists, students, and professionals working in fields such as chemistry, biology, environmental science, and medicine.
Formula of pH pOH H+ OH- Calculator
The calculations performed by the pH pOH H+ OH- Calculator are based on fundamental principles of chemistry. Here are the formulas used:
pH calculation: pH=−log10([H+])pH=−log10([H+])
pOH calculation: pOH=−log10([OH−])pOH=−log10([OH−])
H+ concentration calculation: [H+]=10−pH[H+]=10−pH
OH- concentration calculation: [OH−]=10−pOH[OH−]=10−pOH
General Terms Table
Here are some general terms related to pH, pOH, H+, and OH- that people commonly search for:
| Term | Definition |
|---|---|

Example of pH pOH H+ OH- Calculator
Suppose we have a solution with a hydrogen ion concentration of 1×10−31×10−3 mol/L. Using the Calculator, we can determine the pH of this solution as follows:
pH=−log10(1×10−3)=3
Most Common FAQs
A: pH and pOH values indicate the acidity or basicity of a solution, which is crucial for understanding chemical reactions, biological processes, and environmental conditions.
A: Simply input the known value (either pH, pOH, [H+], or [OH-]) into the corresponding field, and the calculator will automatically compute the other parameters.
A: Yes, the calculator is applicable to any aqueous solution where the dissociation of water into H+ and OH- ions occurs.
