Co(II) was used as an internal standard to analyze a sample of Ti(IV) with atomic absorption spectroscopy (AAS). A standard mixture containing 1.30 µg Co/mL and 1.48 µg Ti/mL measured by AAS produced a signal-to-signal ratio of 2.13 Ti : 1.00 Co. A mixture was prepared by combining 5.50 mL of a Ti(IV) solution of unknown concentration with 3.50 mL of a 13.4 µg/mL solution of Co(II). The absorbance of the mixture at the Ti(IV) wavelength was 0.139 and the absorbance at the Co(II) wavelength was 0.208. Determine the concentration, in moles per liter, of Ti(IV) in the original unknown solution. concentration: M Ti(IV)

"[FeSCN2+]eq is calculated using the formula: [FeSCN2+]eq = Aeq/Astd x [FeSCN2+]std where Aeq and Astd are the absorbance values for the equilibrium and standard sample respectively." I am confused about what Aeq and Astd mean. We did an experiment where we measured the absorption of this chemical formation and I got around 0.18. Is that one of the values?

Consider the analysis of a sample of iron using atomic absorbance spectroscopy. Which of the following statements are true? Select all that apply. The iron sample is aspirated into the flame, where the solvent evaporates and the iron analyte is atomized. The hollow-cathode lamp for iron emits wavelengths of light unique for iron. A detector measures the amount of light generated by the flame and not absorbed by iron. The iron atoms in the flame absorb some of the light emitted from the hollow-cathode lamp. The flame replaces the cuvet of conventional spectrometers and the flame pathlength is typically 10 cm.
