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 7.80 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 250.0 ml and analyzed in a colorimeter. the percent transmittance of the solution was determined to be 52.8%. 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 =1920- x +0.026 what is the absorbance of the permanganate in the diluted absorbance = waste solution? what is the concentration of the permanganate in the diluted concentration of the permanganate = м waste solution? what is the concentration of the mn2+ ions in the original concentration of the mn2+ ions = м waste solution?
