Beer’s Law Lab Hanna Beeter March 15‚ 2013 Honors Chemistry Introduction: In Beer’s law lab the purpose was to find the unknown concentration. The lab included the use of a volumetric flask‚ pipette‚ and spectrophotometer. The spectrophotometer played the biggest part in finding the concentration of the unknown. A spectrophotometer is an apparatus for measuring the intensity of light in a part of the spectrum‚ and is transmitted or emitted on a particular substance. After the number retrieved

Problem: How do protease in some fruit juices help softening meat? Hypothesis: The protease in some fresh juices digests collagen‚ which gives meat a tough texture by holding meat fibres together. Design of investigation: In order to test the hypothesis‚ the presence of protease in those fresh juices was tested at first. Then the amount of them was needed to be compared for finding their difference in effectiveness in tenderizing meat. Control experiments were set up for proving protease was

The experiment was carried out in a Trent University greenhouse for a 14-day period. Ten small glass jars were labelled according to their treatment type (warm or room temperature). Room temperature jars were categorized as 1.1‚1.2‚1.3‚1.4‚ and 1.5‚ then the warm temperature jars were 2.1‚2.2‚2.3‚2.4‚ and 2.5. Jars were filled with a 100ml of federalized water‚ and a mark at the 100ml was made as indication to ensure the correct amount of water was given if the jars needed to be topped up. With a
