As described in part A of the lab, you are preparing a solution by adding 2.00 mL of 0.00200 M KSCN in HNO3 and 25.00 mL of 0.200 M Fe(NO3)3  in HNO3 into a clean, labeled 100.00 mL volumetric flask and diluting to the 100.00 mL mark with 0.25 M HNO3. Calculate the final concentration of KSCN in HNO3.

    3. Experimental Procedure, Part A.1. For preparing a set of standard solutions of FeNCS, the equilibrium molar con- centration of FeNCS is assumed to equal the initial molar concentration of the SCN in the reaction mixture. Why is this assumption valid? A. A Set of Standard Solutions to Establish a The set of standard solutions is used to determine the absorbance of known molar con- centrations of FeNCS2. A plot of the data, known as a calibration curve, is used...
