🎬
Interactive lecture
As you scroll, a live D3 panel animates every idea: H⁺/OH⁻ release, the proton transfer in conjugate pairs, the colour pH scale, salt hydrolysis, buffer curves, and an interactive titration where you add base to acid and watch the pH curve and indicator colour respond.

⚗️
Practical experiment
Run the acid–base titration on a guided 3D bench: add NaOH from the burette, watch the indicator flip and the pH meter jump, then plot the titration curve live with D3. Tap any part of the apparatus for its name, explanation and an Ask AI button.
