"pH" is a measure of the acidity or basicity of a solution in chemistry. It is defined as the negative logarithm (base 10) of the concentration of hydrogen ions in a solution, with a pH of 7 being neutral, lower values indicating acidity, and higher values indicating basicity. The concept of pH was first introduced by Danish chemist Søren Peder Lauritz Sørensen in 1909 as a way to measure the acidity of beer. It has since become an essential tool in many fields of science, including chemistry, biology, and environmental science. pH is important because it affects many chemical and biological processes, including enzyme activity, cell function, and the solubility of minerals. pH can be measured using a pH meter or through the use of pH indicator dyes.

Acid Base Titration Lab Report Discussion
This allows for quantitative analysis of the concentration of an unknown acid or base solution. It makes use of the naturalization reaction that occurs between acids and bases and the knowledge of how acids and bases will react if their formulas are known. Acid-base titration can also be used to find percent purity of chemicals. When a weak acid reacts with a weak base, the equivalence point solution will be basic if the base is stronger and acidic if the…...

Enzyme Activity Lab Report
The reactant an enzyme acts on is referred to the enzyme’s substrate. The enzyme will combine with or to its substrate. While the two are joined, the substrate is converted to its product by catalytic action of the enzyme. There is an active site of the enzyme molecule which is a restricted region that actually attaches to the substrate. Usually the active site is formed by only a few of the enzyme’s amino acids, the rest is just the framework…...
