Beers law solve for E3 and E4 showing work Part II. Equilibrium Constant Calculations Calculate the initial moles of Fe3+ and SCN- for solutions E2 through E6 and record these values in the table on your Data Sheet. You obtain the moles of the reactants by multiplying their molarity by the volume (in L) of their solution used. Determine the equilibrium concentration of FeSCN2+ for each of the solutions E2-E6 from your Beer’s Law plot. Using these equilibrium concentrations, the...
A 25.0 mL volume of 0.0200 M Fe(NO3)3 is mixed with 50.0 mL of 0.00200 M NaSCN and 25.0 mL of 0.100 HNO3. The blood-red FeSCN2+ ion forms and the equilibrium is established: Fe3+(aq) + SCN-(aq) <---> FeSCN2+(aq) The equilibrium concentration of FeSCN2+ ([FeSCN2+]) was measured spectrophotometrically and found to be 7.0 x 10-4 mol/L. To calculate the equilibrium constant (Kc) for thr equilibrium system, proceed through the following steps: A. Moles of Fe3+, initial B. Moles of SCN-, initial...
Thanks! BEER'S LAW EXPERIMENT S PRE-LAB QUESTIONS Fully answer these questions in your laboratory notebook before coming to lab. work for numerical calculations. 1. The wavelength at which a substance absorbs the most light is called the The metal complex Cu(C,N,H)SO, has a purple (violet) color. What would you guess as the value 2. If a solution sample has an extinction coefficient of 7.53 L mol cm,a pathlength of 1.50 cm, and an absorbance of 0.408, what is the concentration...
1. You prepare a mixture to use to create a colorimetry calibration curve for FeSCN2+ by mixing these things in a 25.00 mL volumetric flask and then diluting to the volume of the flask with 0.3 M HNO3. 5.00 mL 0.00200 M NaSCN 10.00 mL 0.30 M Fe(NO3)3 What is the concentration of FeSCN2+ in this mixture? [Pay attention to the values to determine which reactant is being driven to completely react...] 2. You prepare a mixture to use to...
What's the concentration of [FeSCN2+] using limiting reactant theory and equation? For each test tube solution enter the initial concentration of Fe+ and SCNthe equilibrium concentration of FeSCN2: into the ICE table given. Complete entries for the rest of the table and calculate the K value for each of the tables. The values of K should be confined to a narrow range to reflect constancy. Comment on the quality of your work in this regard and calculate the average K....

#1, #3, and #5-7 please!!! Pre-Lab Questions 1. Write the balanced chemical equation for the formation of FeSCN2" from Fe(NO3)3-9H:0 and NaSCN. 2. In this experiment a dilute solution of 0.1 M HNO is used to maintain the ionic strength and low pH needed for the reaction to occur. How is nitric acid classified in terms of MSDS? What are some of the safety concerns regarding the handling of nitric acid? 3. Look at the procedure for making the standard...
