A solution comprised of 100 ml acetone and 100 ml H2O was used to extract and purify the yellow pigment. The pigment solution was then evaporated to a dry powder, dissolved in methanol, and given to the student in this condition. What would be the appropriate blank to use for the spectrophotometric measurements? A. A mixture of equal volumes of acetone and H2O. B. Acetone C. H2O D. Methanol E.
