The Effect of Biological and Nonbiological Material

The Effect of Biological and Non biologic Material on the chemical reaction to a Changing pH Level This prove was conducted to learn exactly how biological material responds to acclivity or dropping pH levels in comparison to how nonbiological material does. The dependent variable in this experiment was how the different materials react, and the independent variable was the type of material, biological or nonbiological. Tap water was the selected nonbiological material, and the generally cognize pH level for water is 7, or neutral.Potato homogenate, liver homogenate and egg white solution was apply as the biological material. A devotee solution that serves as a model of a biological materials chemical that helps it carry out homeostasis was also used in the experiment, being tried and true in the akin manner as the other materials. This topic was tested in order to support a tissues biological chemical processes, presence of buffers, and their ability to maintain its needed p H level for normal function.For actually conducting the experiment, each material was measured out into 25 mL and set up into a beaker to be measured for its pH level with pH paper. Then five drops hydrochloric acid was added to the beaker with a 0. 1M dropper, and then the pH level was measured again. This process was repeated until a total of 30 drops of HCl was added to the beaker. from each one material was tested in this way, and then the same was done with each material, only adding sodium hydroxide with five drops at a clock as well, measuring the pH level each time in between with pH paper.If both biological and nonbiological material are treated in the same way with hydrochloric acid and sodium hydroxide to raise or lower the pH level, then the biological material will claim less of a change in its pH level, because its biological tissues have natural chemical processes that regulate the pH level. If a chemical solution that is a model of a biological buffer is treated with hydrochloric acid and sodium hydroxide to raise or lower the pH level, then it will stay generally the same pH level as its start, because a buffers purpose is to regular the pH level of a biological material.
