Titration Formula

The Formula

n_A = n_B \implies M_A V_A = M_B V_B

When to use: Slowly adding a known solution to an unknown one until the reaction is just complete โ€” the volume used reveals the concentration.

Quick Example

Adding NaOH solution to HCl of unknown concentration until pH = 7 (equivalence point), then calculating HCl concentration.

What This Formula Means

A laboratory technique used to determine the concentration of a solution by reacting it with a solution of known concentration.

Slowly adding a known solution to an unknown one until the reaction is just complete โ€” the volume used reveals the concentration.

Why This Formula Matters

Standard technique in analytical chemistry, quality control, and pharmaceutical testing.
