sci.chem-ph Calculator
Calculates pH from hydrogen ion concentration, weak acid/base equilibria, and buffer solutions using the Henderson–Hasselbalch equation. pH = −log[H⁺] — each pH unit is a 10× change in [H⁺] — blood is tightly regulated at pH 7.35–7.45 by bicarbonate buffering.
Inputs
H Conc
Amount of solute per unit volume. Higher concentration = more solute dissolved.
Results
pH
pH of the solution. Below 7: acidic. 7: neutral. Above 7: basic (alkaline).
pOH
