It was decided to analyze a waste solution that contains an unknown concentration of mn2+ ions using colorimetry. a strong oxidizing agent was added to a 6.40 ml sample of the solution to convert the colorless manganese ions into purple permanganate ions. after the reaction is complete, the solution was diluted to 100.0 ml and analyzed in a colorimeter. the percent transmittance of the solution was determined to be 47.8 %. also a calibration curve was prepared by using a series of solutions with known concentrations of permanganate and the equation for the best fit line was found. y=1560â‹…x+0.024 what is the absorbance of the permanganate in the diluted waste solution? absorbance = what is the concentration of the permanganate in the diluted waste solution? concentration of the permanganate = m what is the concentration of the mn2+ ions in the original waste solution? concentration of the mn2+ ions = m
