Three different digestive fluids are placed in test tubes The fluid placed in test tube #1 was extracted from the mouth. The fluids in test tubes #2 and #3 were extracted from what was believed to be the stomach. 5 mL of olive oil are placed in each of the test tubes, along with a pH indicator. The intial colour of the solutions is red, indicating the prescence of a slightly basic solution. The solution in test tube #3 turns clear after 10 min, but all the other test tubes remain red. Describe the conclusions you could draw from the experiment.
Justify each of the conclusions with the data provided.
(Hint: Consider which substances were digested. What are the structual components?)
