Chemistry 3.2 Determine the concentration of an oxidant or reductant by titration
Subject content
This achievement standard involves analytical chemistry where a volumetric analysis is carried out using data from an oxidation-reduction titration to calculate the composition of an unknown sample.
- Determination of the composition of the sample will involve one mathematical conversion between the concentration of the solution analysed and the composition of the sample, for example:
- concentration of the sample before dilution
- concentration in grams per litre (g L -1) or percentage (%) – w/v
- % composition (or purity) of a solid.
View the following interactive and animated slides of about acids and bases. The topics include a revision of acid and bases, neutralisation, and titration, with some calculations.
Auckland University's site Bestchoice For Chemistry has an option under Course 13, Acid-base - titration curves, that you might find useful. This is a free site, but note that there is a requirement that you login.
