1. Which solvent system gives you two spots that are easily identified by both color AND different distances each spot travelled? Known and Unknown R Values Use the data from Table 2 to calculate the Rf values for each of the metal ions in each of the solvents and for each of the colored spots on the unknown. Remember to round to the appropriate number of significant figures based on your measurements and math!!! Rr Values in Solvent System: Final color of the spot (after B) from the solvent selected in #1. Metal Ion 1 3 Fe+ Cu2+ Co2+ Ni2+ Unknown spot #1 Unknown spot #2 Unknown Identity - use final colors and Rr values from the solvent chosen in #1 Closest known metal ion match by color Closest known Probable metal ion match by Rr Color of the unknown Unknown spot (after B) Rf identity spot known spot #1 known spot #2
Analyzing Infrared Spectra
The electromagnetic radiation or frequency is classified into radio-waves, micro-waves, infrared, visible, ultraviolet, X-rays and gamma rays. The infrared spectra emission refers to the portion between the visible and the microwave areas of electromagnetic spectrum. This spectral area is usually divided into three parts, near infrared (14,290 – 4000 cm-1), mid infrared (4000 – 400 cm-1), and far infrared (700 – 200 cm-1), respectively. The number set is the number of the wave (cm-1).

IR Spectrum Of Anisole
Interpretation of anisole using IR spectrum obtained from IR analysis.
IR Spectroscopy
Infrared (IR) or vibrational spectroscopy is a method used for analyzing the particle's vibratory transformations. This is one of the very popular spectroscopic approaches employed by inorganic as well as organic laboratories because it is helpful in evaluating and distinguishing the frameworks of the molecules. The infra-red spectroscopy process or procedure is carried out using a tool called an infrared spectrometer to obtain an infrared spectral (or spectrophotometer).
