The Effect of Biological and Nonbiological Material
The Effect of Biological and Nonbiological Material on the response to a Changing pH Level This experiment was conducted to learn scarcely how biological material responds to rising or dropping pH levels in comparison to how nonbiological material does. The dependent variable in this experiment was how the polar materials react, and the independent variable was the type of material, biological or nonbiological. Tap piddle was the selected nonbiological material, and the generally known pH level for water is 7, or neutral. tater homogenate, liver homogenate and egg white solution was used as the biological material. A buffer solution that serves as a model of a biological materials chemical that helps it carry out homeostasis was overly used in the experiment, being tried and true in the aforesaid(prenominal) mode as the other materials. This topic was tested in order to digest a tissues biological chemical physical processes, presence of buffers, and their might to maintai n its needed pH level for normal function.For actually conducting the experiment, each(prenominal) material was measured out into 25 mL and put into a beaker to be measured for its pH level with pH paper. Then quin 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. Each material was tested in this way, and then the same was done with each material, only adding sodium hydroxide with five drops at a time as well, mensuration 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 debase the pH level, then the biological material leave alone have little of a change in its pH level, because its biological tissues have earthy chemical processes that regulate the pH level. If a chemical solution that is a model of a bio logical 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.
