Here are some questions with a bit of the data. if any can beanswered from this information great! if not, could someone pleaseexplain how to find this information.
Using your absorbance data, calculate Æ, the molar extinctioncoefficient for your complex (A = Ælc) (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 thestoichiometric ratio
Percentage purity of your complex
Based on the % purity, what is the correct range of values forthe value of ε which you calculated earlier? (Hint: think aboutpercentage error!)
Part III – Titrimetric analysis of the coordinationcomplex
Concentration of HCl solution, 0.05 mol/L
Determination Number | Complex Mass (g) | Consumed HCl volume (mL) |
Determination 1 | 0.280 g | 4.5 mL |
Determination 2 | 0.300 g | 4.2 mL |
