Spectrophotometry and the Beer–Lambert Law
Spectrophotometry is a technique that uses light absorption to measure the concentration of an analyte in solution. The amount of light absorbed by a solution is related to the analyte concentration by the Beer–Lambert law, which is expressed as follows: A = εbc, where ε is the molar absorptivity of the analyte, b is the path length (the ...

USNCO/NJSL topics this is usually done using spectrophotometry and absorbance with essentially the same method the maximum point represents the stoichiometric ratio because precipitate is produced with neither reactant in excess, so they are basically reacting at exactly their molar ratio #chemistry #chem #study #tutorial
