pH Calculator
pH from H⁺ Concentration
H⁺ from pH Value
Formula
pH = -log₁₀[H⁺] | pOH = 14 - pH | [H⁺] = 10^(-pH)
Frequently Asked Questions
What is pH?
pH = -log₁₀[H⁺]. It measures how acidic or basic a solution is on a scale of 0-14. pH 7 is neutral (pure water). Below 7 is acidic, above 7 is basic. Each whole pH unit = 10× difference in H⁺ concentration.
