3. In the example above, when the available sugar was used up, what happened in the tube and what accounted for the rise in pH? (Circle all that apply) a. Initially the neutral tube became acidic as the glucose was broken down. b. After several days the tube converted to a neutral by product or the other break down products neutralized the initial products. c. Initially the neutral tube became basic as the glucose was broken down. d. This tube has fundamentally been neutral the entire time. e. The change in tube color is the result of the methyl red indicator showing macroscopically the presence or absence of H+ ions. 2. The data below shows the pH changes in a glucose phenol red broth over an eight day timeframe. Create a table and graph in the computer. Attach the table and graph completed in a software program in order to get for full credit on the lab. (3 pts) Phenol Red Broth Over Time Day 1 - pH 7.0 Day 5 - pH 7.0 Day 2 - pH 6.0 Day 6 - pH 7.5 Day 3 - pH 5.5 Day 7 - pH 8.0 Day 4 - pH 6.5 Day 8 - pH 8.5
