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…...

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…...

The completion of a reaction can be seen by a change in color or when the pH remains constant. The equivalence point during titration is when both solutions are present in equal amounts. The end point of the titration is when the reaction has been completed, which is usually marked by a change in color. One researchable question relating to acid/base titration would be what strengths of acids and bases react with each other during titration, and what kind of…...

Introduction Soil pH can be tested in a number of ways. The measurement of pH is the most common chemical measurement in soil, biology and aqueous solutions (Bohn et al. ). The most common ways are either using an electrochemical tester, where electrodes that are capable of detecting hydrogen ions, are placed in the solution to be tested and the pH displayed on a digital display. The other method, BDH, involves creating a suspension and comparing its colour to a…...

Introduction: Substances, even household substances, can be acidic, basic, or neutral. Acids and bases are called aqueous solutions, or mixtures of certain substances dissolved in water. The amount of acidity or basicity can be measured by using the pH scale. The scale runs from 1-14. The scale has to do with the amount of hydrogen ions [resent in a substance. Hypothesis: Our hypothesis for this experiment consists of twelve different substances.Essay Example on Ph Lab Report Sample The tomato juice…...
