Titration of Strong and Weak Acids


Learning Objectives:

Students practice titration of acidic solutions, using a pH meter to measure the end point.

Procedures:

Students perform titration of acidic solutions - hydrochloric acid and acetic acid - with a basic solution - sodium hydroxide - as a titrant. They use both an indicator and a pH meter to measure the neutralization point, and obtain a titration curve. Students can then determine a precise end point from this graph, and can calculate the concentrations of the acidic solutions.
