Multiple Choice O 25 degrees Celsius 130 degrees Celsius O degrees Celsius 109 degrees Celsius 45 degrees CelsiusFlame Test (Unknown) View the Unknowns to see the results of the flame test. Record Your Observations (clearly and neat hand writing please)C. Spectrophotometric Measurements of the Hill Reaction 1. Place 15 mL of the 0.05-mg chlorophyll/ mL suspension in a test tube. Wrap the tube with aluminum foil and chill in an ice bucket. This is the source of unheated chloroplasts. 2. Place the remaining 10 mL of the 0.05-mg chlorophyll/mL suspension in a test tube and heat until boiling using an alcohol lamp. Heating inactivates the chloroplasts. Stand the heated mixture for 5 min. to allow the debris to settle.
