pH Buffer Solution: Henderson-Hasselbalch & Capacity (2D)

Interactive 2D pH buffer simulator: tune pKa and the weak-acid/conjugate-base ratio with the real Henderson-Hasselbalch equation, titrate in strong base and watch the titration curve's flat buffering region give way to a sharp equivalence-point jump, with a live buffer-capacity meter.

This 2D simulator builds a weak-acid/conjugate-base buffer from scratch: pick a pKa, set the HA/A⁻ ratio, and watch the live pH follow the real Henderson-Hasselbalch equation. Titrate in strong base to trace out the full titration curve — a flat buffering plateau around pKa that gives way to a sharp equivalence-point jump once the weak acid is used up — while a buffer-capacity meter shows exactly how much resistance to pH change is left at each point.
