Definition of Colorimetry and calibration curves
Check what you remember
Read the wording for your board, then hide it and explain Colorimetry and calibration curves in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
React the sample to produce a coloured product, measure absorbance with a colorimeter, and plot absorbance against concentration for standard solutions to link absorbance to known concentrations.
