4 Strong and weak acids (HT only)
The volumes of acid and alkali solutions that react with each other can be measured by titration using a suitable indicator.
Students should be able to:
- describe how to carry out titrations using strong acids and strong alkalis only (sulfuric, hydrochloric and nitric acids only) to find the reacting volumes accurately
- (HT Only) calculate the chemical quantities in titrations involving concentrations in mol/dm3 and in g/dm3.
AT 8 Use of appropriate qualitative reagents and techniques to analyse and identify unknown samples or products including gas tests, flame tests, precipitation reactions, and the determination of concentrations of strong acids and strong alkalis (links to A-level AT d).
