A student determined the reacting volumes of hydrochloric acid
and sodium hydroxide solution by titration.
This is the method used.
1. Measure 25.0 cm3
of the sodium hydroxide solution.
2. Add the sodium hydroxide solution to a conical flask.
3. Add 3 drops of indicator to the sodium hydroxide solution.
4. Add the hydrochloric acid drop by drop until the indicator changes colour.
5. Record the volume of the hydrochloric acid added.
6. Repeat steps 1 to 5 three more times.
0 2 . 3 Which piece of equipment should be used to measure 25.0 cm3
of
the sodium hydroxide solution in step 1? [Show Less]
