Introduction
1.) Colorimetry
An analytical technique in which the concentration of an analyte is measured by its ability to produce or change the color of a solution
Changes the solution’s ability to absorb light
2.) Spectrophotometry
Any technique that uses light to measure chemical concentrations
A colorimetric method where an instrument is used to determine the amount of analyte in a sample by the sample’s ability or inability to absorb light at a certain wavelength.
