Technique that measures absorption of light by a coloured solution
Greater absorbance
Compare absorbances of known concentrations to find unknown concentration
Colour transmitted through solution
Red light
Red filter (complementary colour)
Use distilled water blank, set absorbance to zero
x-axis: concentration, y-axis: absorbance
¾ full
Find absorbance on y-axis → horizontal line to curve → vertical line down to x-axis concentration
