pH pOH H+ OH- Calculator Online

Show Your Love:

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=−log⁡10([H+])pH=−log10​([H+])

pOH calculation: pOH=−log⁡10([OH−])pOH=−log10​([OH−])

H+ concentration calculation: [H+]=10−pH[H+]=10−pH

OH- concentration calculation: [OH−]=10−pOH[OH−]=10−pOH
