HCl Strength (Conductometric)

Determine unknown concentration of HCl by titration with standard NaOH using conductivity data.

Volume of NaOH at equivalence (mL)

Normality of NaOH (N)

Volume of HCl sample taken (mL)

---

N_HCl = (V_NaOH × N_NaOH) / V_HCl

Based on equivalence: moles of acid = moles of base.

In conductometric titration, the equivalence point is the intersection of two linear segments.
Ensure volumes are in the same units (mL).
If the acid is diprotic, the formula still holds because normality accounts for equivalents.
