If some of the water-soluble contents found in all of the fruits tested in Experiment 2 absorbed

Question:

If some of the water-soluble contents found in all of the fruits tested in Experiment 2 absorbed light of the same wavelength as the compound formed with sulfite and the coloring agent, how would the measurements have been affected? Compared to the actual sulfite concentrations, the sulfite concentrations apparently measured would be:
F. Higher.
G. Lower.
H. The same.
J. Higher for some of the fruits, lower for others.


Experiment 2
A 100 g fruit sample was ground in a food processor with 50 mL of H2O and the mixture was filtered. The food processor and remaining fruit were then washed with H2O, these washings were filtered, and the liquid was added to the sample solution. The coloring agent was added and the solution was diluted to 100 mL. The procedure was repeated for several fruits, and the absorbances were measured (see Table 2).
