        Colorimetry/accurate dilution
        Colorimetry uses the relationship between colour intensity of a solution and the concentration of the coloured species present.
        A colorimeter/spectrophotometer is used to measure the absorbance of light which is the complementary colour to the colour of the solution.

Challenging Plants: Fertilisers - Practicals

In association with Reckitt Benckiser

Nutrients essential for plant growth are obtained naturally from soil or other growing media. However, supplies become depleted and fertilisers are needed to increase the availability of nutrients to plants. An understanding of chemical changes is used to making fertilisers, often designed to meet specific requirements such as particular nutrient ...
