Acid-Base Toolkit

Acid–Base Toolkit is a compact chemistry companion for calculating and exploring aqueous acidity. Whether you are in class, reviewing for exams, or checking numbers in the lab, you get conversions and explanations in one clean interface.

What’s inside

pH from [H⁺] — Compute pH from hydrogen ion concentration with clear formulas and optional step-by-step working.

pOH & related pH — Work from hydroxide concentration and relate pOH to the full acid–base picture.

Relations — Convert between pH and pOH, and between [H⁺] and [OH⁻], using the water-ion product and standard identities. Pick the direction you need (e.g. pH → pOH, [H⁺] → [OH⁻]).

Acid–base scale — Interpret a pH value on the scale: acidic, neutral, or alkaline, with contextual labels.

Strong acids & bases — Approximate pH/pOH for strong monoprotic acid and strong base solutions from concentration (idealized model).

Reference — Handy summaries and reminders while you calculate.

Designed for clarity

Readable results with optional calculation steps

Adjustable precision and scientific notation in settings

History of recent calculations you can revisit

Presets to save and reload common setups

Calculations follow standard introductory chemistry conventions. This app supports learning and quick checks—it does not replace laboratory procedures, calibrated instruments, or professional advice where safety or compliance matters.

Offline-friendly once installed—no account required.
