Select Reagents & Titration Setup

1. Choose Reaction System
In this lab, (25.0 cm3 in conical flask) is titrated against (in burette).
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)
2. Standard Solution & Molarity

Sets the unknown concentration. Repeat trials use the same target; the average titre is calculated from your recorded readings.

3. Choice of Indicator pH 8.3 – 10.0
