Acid-Base Neutralization Reaction (2D)

This 2D simulator drips a strong base from a burette into a beaker of strong acid, one virtual mole at a time. As the titrant volume rises, the panel tracks the exact pH from the remaining acid or base excess, colors the beaker liquid by whichever indicator you pick — universal, phenolphthalein, bromothymol blue, or litmus — and reports how far the reaction sits from the equivalence point where H⁺ and OH⁻ have exactly cancelled into salt and water.
