Chem lab report

1. a suitable indicator should be used. Strong acid-weak base titration and weak acid-strong base titration gives different pH in end point, so a suitable indicator is very critical. Sometimes pH probes or other detectors can be used for end-point determination.

2. volume of titrant used. The volume used cannot be too much or little, usually around 10 ml or 25 ml. Otherwise, concentration should be adjusted.

3. Sometimes background of the solution may affect the end point determination.

4. There are a lot of reference about acid-base titration.
