Determination of an Unknown Concentration of Potassium Manganate using Colorimetry Introduction The purpose of this experiment is to conclude the concentration of an unknown solution using colorimetry to plot a calibration curve. Colorimetry measures the

Notice, the concentration is known to the nearest 0.001 M , so this is very precise. Basically, in a titration, we have to find out what volume of the 0.100 M AgNO3 is needed to just precipitate all the Cl-ions in the sample solution. We must also put a p

The sample concentration will be obtained from the standard curve since the OD value of the sample corresponds to a concentration value on the x-axis. The obtained concentration value should be multiplied with the sample dilution factor. Samples yielding
