How do I calculate [SCN-]i given that:
Stock [Fe3+] = 0.00200 M
Stock [SCN-] = 0.00200 M
[Fe+3] [SCN]: of Table 2. Initial Data to Determine Keq Trial Volume Volume Total | Absorbance of Fe+3 volume KSCN(mm) (mm) (mL) hao 5.00 10.00 10.110 | 2 200 5.00 10.00 0.225 3 3.00 5.00 10.00 0.359 4 4.00 5.00 10.00 0.479 5 5.00 5.00 10.00 0.626 11.00×10 -3 2.00x104
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....

help with finding the equilibrium of [Fe(SCN)^2+] morality value
Equilibrium Solutions Data 1. Use your "Absorbance of Solution" values and the graph you made above to interpolate the "Equilibrium [Fe(SCN)]" molarity values. 2. Calculate both the "Initial [Fe ]" and the "Initial [SCN']" molarity values using then dilution equation CiVi C2V2. 3. Calculate the "Equilibrium [Fe ]" molarity values by subtracting the "Equilibrium [Fe(SCN) " molarity values from the "Initial [Fe'" molarity values. 4. Calculate the "Equilibrium [SCN']" molarity values...
