The standard curve was made by spectrophotographic analysis of equilibrated iron(III) thiocyanate solutions of known concentration. You are asked to analyze a Fe(SCN)2+ solution with an unknown concentration and an absorbance value of 0.104 . The slope-intercept form of the equation of the line is ?=4594.4?+0.0042 . The unknown was analyzed on the same instrument as the standard curve solutions at the same temperature. What is the Fe3+ concentration of the unknown solution?

solve all 3 dont waste my answer
1. Check Beer's Law by plotting absorbance vs molar concentration using 2. Is Beer's Law valid for this system? Explain your answer. 3. If Beer's Law is valid, the value of "E" should be constant. Use A-ECPL or E = A/(EL) and the data from Table II to calculate values of E for the five solutions below. The value of L is normally 1 cm so E - A/C in this experiment. Table...
