Testing the pH of Common Household Substances Lab Background Information: The pH scale is used to determine the acidity or basicity level of liquid solutions. If a solution scores a pH level of 1-6 it is an acidic solution‚ 1 being the most acidic and 6 being the least acidic. If a solution rates a pH level of 7 it is a neutral solution‚ meaning it is neither an acidic nor a basic solution. Lastly‚ if a solution is 8-14 on the pH scale it is a basic solution‚ 8 being the least basic and 14 being

Acid-Base Titration Using a pH Meter Bradley Holloway and Jennifer Parker Period 6 April 16‚ 2013 Introduction: In chemistry‚ the ability to find molarities of acidic and basic solutions is a convenient way to convert between moles of solute and the volumes of their solutions. Through the process of titration‚ the molarity of these acids and bases can be found to a high level of precision. To begin titration‚ one solution is added to a second solution slowly until a certain point

There had to be an initial force to set the universe into motion. Einstein refers to this force as “the cosmological constant”. This constant corrected Einstein’s theory of relativity to explain the movement of the universe. Originally Einstein believed that the universe was static even though his mathematical theories suggested

Factors affecting Enzyme Activity: The effect of pH on enzyme activity Background Knowledge: An enzyme is a biological catalyst – which speeds up the reaction rate‚ without itself getting altered. Enzymes are proteins with long polypeptide chains that are folded up into three – dimensional shapes. An enzyme acts on a substrate to convert the substrate into a product useful for the organism.The active site is a special region on the surface of the enzyme where the substrate binds to the enzyme.
