Acid Base Titration Lab Report Discussion
Words • 374
Pages • 2
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
Words • 868
Pages • 4
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…...

My hypothesis for these solutions is ammonia is acid, vinegar is neutral, rain cleaner is base, soft drink is base, baking soda is base, detergent is base, and lemon juice is an acid. For the red cabbage it would be the same as using red and blue litmus. If the pH number of the solutions is less than 7 then lemon juice is the only that is acid but it’s weak. If the pH number of the solutions is greater…...

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…...

A buffer is a special solution that stops massive changes in pH levels. Every buffer that is made has a certain buffer capacity, and buffer range. The buffer capacity is the amount of acid or base that can be added before the pH begins to change significantly. It can be also defined as the quantity of strong acid or base that must be added to change the pH of one liter of solution by one pH unit. The buffer range…...
