Titration Simulator

This interactive simulator explores Titration Simulator in Chemistry. Add base to acid. pH curve in real time. Find equivalence point. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.

Who it's for: For learners comfortable with heavier math or second-level detail. Typical context: Chemistry.

How it works

Add **strong base** from a burette into a flask of **acid**. The **pH curve** shows how pH changes with titrant volume. For **strong–strong** titrations the equivalence point is at **pH 7**. For **weak acid / strong base**, the equivalence region is **basic** because the conjugate base hydrolyzes. Use **Jump to V_eq** to land on the stoichiometric point.

Key equations

Strong–strong: [H⁺] = (C_a V_a − C_b V_b) / (V_a + V_b) before equivalence; after, use [OH⁻] similarly. At C_a V_a = C_b V_b → pH 7.
Weak acid buffer: pH = pK_a + log([A⁻]/[HA]). At equivalence: [OH⁻] ≈ √(K_b · [A⁻]).
