The fluorescence quantum yield is the ratio of the number of photons absorbed to the number of photons emitted.
In titration analysis, the sudden change of indicator color is generally used to determine the arrival of stoichiometric point, and the titration is stopped when the indicator changes color. This point is called ( ).
Emission spectra vary widely and are dependent upon the chemical structure of the fluorophore and the solvent in which it is dissolved.
3. In the KMnO4 method, the KMnO4 solution can be filled with a basic burette for titration.
