SOLVED: Question 82 pts1) Explain the principle of the method of standard addition (MSA) to quantify an analyte.2) Describe in detail how Yu process the data when using MSA and how you will determine the concentration of analyte in the sampl (when using MSA

SOLVED: Multiple standard addition method was used for determining Fe in a natural water sample. Ten-milliliter aliquots of the sample were pipetted into 50.00-ml volumetric flasks. Exactly 0.00, 10.00, 15.00, and 20.00 ml of a standard solution containing 11.1 ppm of Fe3 were added to each flask, followed by an excess of thiocyanate ion to give the red complex Fe(SCN)2 . After dilution to volume, the absorbance of the five solutions was measured in a 982-cm cell at 480 nm and found to be 0.240
