Caption

Nickel ions (Ni2+) in solution. This is an example of a transition metal complex that can be analysed through colorimetry. Colorimetry is a means of identifying the concentration of a coloured solution by passing light through it and noting how much of each wavelength is absorbed (spectral absorption). This enables the concentration to be identified by cross-referencing the results with those from solutions of known concentration. Colorimetry is similar to spectrophotometry but deals with tristimus values. The tristimus values of a colour are the amounts of the three primary colours needed to make up that colour.
