PH Fermintation
In our experiment with pH, we did three replicates, hoping for accurate readings. By doing, three replicates we found out results had variations. Our hypothesis states if the rate of fermentation is dependent on pH, in acidic pH the reaction will happen at a faster rate. From this statement out hypothesis is partially correct. The acidic pH3 never reacted at a fast rate. After the first five min interval in test one, it dropped 7mm and stayed at that measurement throughout the test. In test two for pH3, the water dropped 4mm and stayed at the same measurement throughout the test. In test three for pH3, the water dropped 6mm and once again stayed at this measurement throughout the test. From out three tests our hypothesis was not true. The acidic pH3 never moved at a fast rate. The acidic pH5 was true the hypothesis in the three tests we did. The acidic pH5 moved at a fast rate and reacted faster. In test one pH5, the water level dropped every five min. interval. It dropped 4-5mm each interval. In test two, pH5 stayed at 13mm
