Using colorimetry, you decide to analyze a waste solution that contains an unknown concentration of mn2 ions. you add a strong oxidizing agent to a 7.90 ml sample of the solution to convert the colorless manganese ions into purple permanganate ions. after the reaction is complete, you dilute the solution to 250.0 ml and analyze the solution in a colorimeter. you determine the percent transmittance of the solution to be 51.0%. you also prepare a calibration curve by using a series of solutions with known concentrations of permanganate and find the equation below for the best fit line.
y= 1.10x103 x + 0.026
what is the absorbance of the permanganate in the diluted waste solution?
what is the concentration of the permanganate in the diluted waste solution?
what is the concentration of the mn2 ions in the original waste solution?
