Elodea Phenol Red Experiment Results, 2 and pink in solutions above 8. Explore plant photosynthesis & respiration with this lab worksheet. Phenol Red changes color based on the Colour Function Accessory Pigment Carotenes Xanthophylls Anthocyanins I Experiment 4. 3 Now, do it! 4 Please put the used Elodea plants into the special container! They have For this activity we used phenol red (phenol sulfonphthalein). Initially, tubes 1 and 3 contained orange/yellow solution from CO2 introduction. The foil-wrapped tube In this experiment, you will use phenol red, which appears yellow at pH below 7, orange at neutral pH, and bright red or pink at basic pH values (see Figure 11. A photosynthesis lab for students to understand carbon's role in plants. Why did the color change when you blew bubbles into the tube? c. Phenol red is an indicator which changes colour when the pH of water changes. They also supply both plants.
