Here are some questions with a bit of the data. if any can be answered from this information great! if not, could someone please explain how to find this information.
Using your absorbance data, calculate Ɛ, the molar extinction coefficient for your complex (A = Ɛlc) (refer to Eq 6)
PART III - Titrimetric Analysis of the Coordination Complex
[Cu(NH3)4]SO4.H2O (aq) +4HCl (aq) → Cu 2+ (aq) + 4NH + (aq) + 4Cl − (aq) +SO 2− (aq) +H2O (l) 44
Mass of the complex for both determinations using the stoichiometric ratio
Percentage purity of your complex
Based on the % purity, what is the correct range of values for the value of ε which you calculated earlier? (Hint: think about percentage error!)
