What is pH?

pH is a measure of the acidity or basicity of an aqueous solution. It's defined as the negative logarithm of the hydrogen ion concentration. The pH scale ranges from 0 to 14, with 7 being neutral.

How to Use the pH Calculator

Select the ion type (H⁺ or OH⁻), enter the concentration in mol/L, and click Calculate. The tool will display the pH, pOH, and solution type. Use the Reset button to start over.

Understanding Acids, Bases, and pH

Acids have pH values below 7, while bases have pH values above 7. The pH scale is logarithmic, meaning each unit represents a tenfold difference in hydrogen ion concentration.

pH Scale and Practical Applications

pH measurements are crucial in various fields including chemistry, biology, medicine, and environmental science. They help in water quality testing, food safety, and chemical reactions.
