sci.ph-strong-acid-base Calculator
Calculates pH of strong acid or strong base solutions from concentration, including self-ionisation correction below 10⁻⁶ M. At 10⁻⁷ M HCl, water's own H⁺ contribution is significant — pH is not 7 but ≈6.79, calculated by solving the charge balance equation.
Inputs
Concentration Mol L
Amount of solute per unit volume. Higher concentration = more solute dissolved.
Acid Or Base
Reference formula or conversion factor shown for context.
Results
pH
pH of the solution. Below 7: acidic. 7: neutral. Above 7: basic (alkaline).
pOH
Reference formula or conversion factor shown for context.
[H⁺] (mol/L)
Reference formula or conversion factor shown for context.
[OH⁻] (mol/L)
Reference formula or conversion factor shown for context.
neutral pH at 25°C
pH of the solution. Below 7: acidic. 7: neutral. Above 7: basic (alkaline).
pH + pOH = 14
pH of the solution. Below 7: acidic. 7: neutral. Above 7: basic (alkaline).
