LAB: One Tube Reaction Part 1
AP Chemistry LAB: One Tube Reaction Part 1 Objective: To monitor and document the chemical changes occurring in a single test tube containing a predetermined mixture of chemicals. Materials: test tube, iron nail, sodium chloride, copper (II) sulfate, distilled water, glass stirring rod, tissue paper, parafilm wax Procedures: 1. Label a test tube to identify your group 2. Fill approx. 1/3 of the test tube with copper (II) sulfate crystals. Gently tap the tube to allow the crystals to settle. 3. Using a glass stirring rod, carefully cover the crystals with a layer of Kimwipe tissue paper. 4. Slowly, and with as little disturbance as possible, add enough distilled water to just cover the paper and blue crystals. 5. Repeat the process for the sodium chloride, filling approx. 1/3 of the test tube. Gently tap the tube to allow the crystals to settle. 6. Push more tissue paper into the test tube on top of the white crystals. 7. Add enough water to cover the tissue paper and white crystals. 8. Obtain an iron nail and expose the surface by rubbing with sand paper. 9. Carefully slide the nail into the test tube. 10. Continue adding water until the nail is completely covered. 11. Cover the test tube with parafilm wax and record your Day 1 observations. 12. Return the test tube to the test tube rack. 13. Continue to monitor and record your observations for the next several days, as indicated in the data table. Data: 1. Complete the NFPA label for the two chemicals used in this lab.

Crucible “Lab Instructions” by Ashley Kajioka is licensed under CC BY 4.0 Using your crucible tongs, practice the following techniques on the cool crucible: Lifting the lid from the crucible Placing the lid ajar so that the crucible is slightly open, but the lid will not fall off, as in Figure 5. Quickly, but gently, pushing the lid from its ajar position to completely cover the crucible Lifting the crucible, with its lid, from the clay triangle Carrying the crucible and lid while supporting from underneath with your wire gauze. Practicing these techniques may seem silly, but it is worth your time to do so. Would you rather repeat a trial because you dropped a crucible, shattering it into a million pieces? With your covered crucible in the clay triangle, fire the crucible for 3-5 minutes.

Uv and Visible Spectroscopy1
Page 1 of 4 I. INTRODUCTION TO UV AND VISIBLE SPECTROSCOPY1 When white light passes through or is reflected by a colored substance, a characteristic portion of the mixed wavelengths is absorbed. The remaining light will then assume the complementary color to the wavelength(s) absorbed. Thus, absorption of 420-430 nm light renders a substance yellow, and absorption of 500-520 nm light makes it red. Green is unique in that it can be created by absorption close to 400 nm as well as absorption near 800 nm. When sample molecules are exposed to light having an energy that matches a possible electronic transition within the molecule, some of the light energy will be absorbed as the electron is promoted to a higher energy orbital. An optical spectrometer records the wavelengths at which absorption occurs, together with the degree of absorption at each wavelength. The resulting spectrum is presented as a graph of absorbance (A) versus wavelength. Absorbance usually ranges from 0 (no absorption) to 2 (99% absorption), and is precisely defined in context with spectrometer operation. Because the absorbance of a sample will be proportional to the number of absorbing molecules in the spectrometer light beam (e.g. their molar concentration in the sample tube), it is necessary to correct the absorbance value for this and other operational factors if the spectra of different compounds are to be compared in a meaningful way. The corrected absorption value is called "molar absorptivity", and is particularly useful when comparing the spectra of different compounds and determining the relative strength of light absorbing functions (chromophores).
