Solutions titration and

This part will call upon what you learned in Unit 3, Solutions and Solubility. In particular, you will review solutions, titrations, and acid-base chemistry. 

An oxidation-reduction indicator is a substance which can mark the sudden change in the oxidation potential in the neighbourhood of the equivalence point in a redox titration. The ideal redox indicator will be one with an oxidation potential intermediate between that of the solution titrated and that of the titrand. A redox indicator is a compound which exhibits different colours in the reduced and oxidised forms.
