Titration Simulator 2.0

🧪 Acid-Base Titration Theory

Titration is a fundamental quantitative analytical technique used to determine the unknown concentration of an analyte by reacting it with a standard solution (titrant) of known concentration.

Advanced Research Methodology:

This simulator utilizes Ionic Mobility Summation. Conductivity is calculated as $\kappa = \sum (C_i \cdot z_i \cdot \lambda_i)$, accounting for the Dilution Effect as the total volume increases, providing research-grade accuracy unmatched by standard online tools.

Key Equations & Principles

Expert FAQ & Concepts

1. Why does the pH change so rapidly near the equivalence point?

Near the equivalence point, the analyte is almost exhausted. Even a fractional drop of titrant causes a massive logarithmic shift in $[H^+]$ concentration as the solution transitions from acidic to basic.

2. What is the difference between End Point and Equivalence Point?

The Equivalence Point is the theoretical stoichiometric completion of the reaction. The End Point is the physical point where the indicator actually changes color.

3. Why use Conductometric Titration?

It is superior for titrating very weak acids ($K_a < 10^{-7}$), turbid solutions, or colored liquids where visual indicators like Phenolphthalein are impossible to observe.

4. How does a diprotic acid show two "steps"?

It has two separate protons with distinct $K_a$ values. The first $H^+$ is neutralized completely before the second begins to react, provided $K_{a1} \gg K_{a2}$.
