Using given Concentration and Absorption ,
graph to show the absoprtion spectra of CoCl2. Graph the absorption
asa function of wavelength.
Homework Answers
Solution:
Plot the colorimetric assay curve from given values of absorbance and concentration i.e.
| Concentration (mg/L) | Absorbance |
| 0.200 | 0.615 |
| 0.150 | 0.486 |
| 0.100 | 0.318 |
| 0.050 | 0.139 |
When you plot the curve , you will get a straight line equation
i.e y = 3.192x - 0.0095
now solve for y = 0.643
i.e. 0.643 = (3.192x) - 0.0095
x = (0.643+0.0095) / 3.192
x = 0.204
So 0.204 mg/L is the concentration at absorbance of 0.643

7. The lead level in a sample of contaminated soil was determined using atomic absorption spectrometry. A 2.0 g sample was dissolved in acid and then diluted to a total volume of 50.0 mL. The absorbance of this solution, determined in a spectrometer set at a wavelength of 218 nm, was found to be 0.20. Several standard solutions of lead were tested under the same conditions and the calibration curve shown below was generated. The concentration of lead in the...
