pH & pOH CalculatorLive
acids, bases, and the pH scale
pH
3.0
acidic
0714
Controls
pH measures hydrogen-ion concentration on a logarithmic scale. Each unit is a 10× change — pH 3 is ten times more acidic than pH 4.
Presets
Data Inspector
pH3.00
pOH11.00
[H⁺]1.0e-3
[OH⁻]1.0e-11
Governing equation
Reading this result: Acidic: [H⁺] of 1.0e-3 M outnumbers OH⁻, and because pH + pOH always sums to 14, the pOH here is 11.0.

Acid–Base TitrationLive
pH curve · equivalence point
Controls
Add base to an acid and track the pH. The steep jump marks the equivalence point, where moles of acid equal moles of base.
Presets
Data Inspector
Equivalence50.0 mL
Typestrong acid + strong base
pH at eq.7.0
Governing equation
Reading this result: Equivalence sits near 50.0 mL; because this is a strong acid with a strong base, the pH there is exactly 7 and the jump is nearly vertical.
