Prepare two separate solutions of methyl orange by diluting 3-4 drops of stock solution (bench reagent) in 10mL of distilled H2O in a beaker (color should be just noticeable by eye). 2. Acidify one solution by addition of 1-2 mL of dilute hydrochloric acid (HCl), mix with a clean glass rod and label it as sample A. Note the color change. 3. Add 1-2 mL of dilute sodium hydroxide (NaOH) to the other solution, mix with a clean glass rod and label it as sample B. Note the color change. 4. Using a clean dropper to carefully transfer 1mL of each solution to a cuvette. 5. Obtain absorption spectra in the 250-700 nm range for each solution. Get help from your Teaching Assistant when you use the spectrometer. A blank spectrum is first recorded using a cuvette containing just distilled H2O. It is only necessary to acquire the blank once. 6. Make sure to rinse carefully the cuvette with distilled H2O between measurements. 7. Note that the absorbance must not be greater than 1.0. If necessary dilute the sample and record the dilution factor you used. 8. Save the spectra to a USB key
