PRACTICUM VII PHOTOSYNTHESIS Tools and materials 1. AUDUS photosynthesis apparatus 5. Seal type/wax/vaseline 2. Statives, clamps and clamp clamps 6. Hydrilla verticillata plant 3. 3 chemical glasses 7. Aquadest, sewer water, well/tap water 4. pH meter, thermometer, watch Ways of working 1. Put the hydrilla in the lid upside down (base of the plant facing up). 2. Fill the supply tank with distilled water until it is full, then insert the lid containing plants into the water tube and place the stopper tightly against the wall water tube, add wax/type seal/vaseline. 3. All devices are installed on the stand and make sure the supply tube has a position higher. 4. Use a Hoffman clamp to prevent the rapid flow of water from the stock tube, and try to remove the air bubbles in the capillary tube before the experiment begins. 5. Fill the beaker with clean water (distilled water) and place the thermometer in it. 6. Place the experimental device in a place that gets sunlight. Note the time Experiment and pay attention to the water temperature 7. If the air in the capillary tube is full but the experiment has not been completed, the air can be removed by opening the Hoffman clamp slightly. 8. The same treatment was also carried out for experiments using water media dirty/sewer water and normal well/tap water). Measure the pH of the three water samples.
