To draw a calibration curve, prepare solutions of known concentrations, measure their absorbances using a colorimeter, plot absorbance (y-axis) against concentration (x-axis), and then use the curve to find the concentration of an unknown sample by its absorbance.
- prepare solutions of known concentrations - measure absorbances using colourimeter - plot graph with absorbance on y axis and concentration on x axis - draw curved line graph - measure absorbance using colourimeter - find concentration using the curve
