About Acid-Base pH, pOH & Buffer Solution Studio
An interactive acid-base chemistry studio. Calculate pH, pOH, hydronium ion concentration [H+], and hydroxide ion concentration [OH-] across the 0-14 scale. Features colorimetric pH indicator visuals, real-world substance benchmarks, and Henderson-Hasselbalch buffer calculations.
Key Capabilities & Features
- Two-way conversions: pH ↔ pOH ↔ [H⁺] ↔ [OH⁻]
- Interactive colorimetric pH indicator bar (red for strong acid to blue for strong base)
- Classification badges (Strongly Acidic, Weakly Acidic, Neutral, Weakly Basic, Strongly Basic)
- Buffer solution solver via Henderson-Hasselbalch equation (pH = pKa + log([A⁻]/[HA]))
- Preset benchmarks (Stomach Acid, Pure Water, Blood, Bleach, Ammonia)

Frequently Asked Questions
What is the relationship between pH and pOH?
In aqueous solutions at 25°C, pH + pOH = 14.00, derived from the self-ionization constant of water (Kw = 1.0 × 10⁻¹⁴).
