I need help writing a discussion for the biology lab report that i'm doing. If anyone could help in explaining the results it would be much appriciated. Here's the experiment..... We had 6 flasks each containing yeast, sugar and water. 2 of the six we added 5ml of 1.0 M HCl and into two others 5ml of 1.0 M NaOH was added. This created 2 acidic environments, 2 neutral environments and 2 basic environments. One of each type of environment was set to grow in anaerobic conditions and the other in aerobic conditions. The intial pH of the solutions were: Acidic=2, Neutral=7, Basic=10. Our experiement was meant to see if the yeast growing in either an aerobic or anaerobic condition would effect the pH of the solution. The results were that all six flasks had an ending pH of 3. Are these results the ones we should have got, or did we screw up the experiment somewhere along the way?? It seems to me that these shouldn't be the results, but if anyone knows differently please let me know. Any insight would be helpful!!!
