To determine if the reaction had gone to completion‚ a Starch/Iodine test was conducted. A change in the strip to a deep blue color would signal an excess of sodium hypochlorite reagent present. An excess is the reagent symbolizes the end of the reaction because there is no longer any reactant left to consume reagent. After the reaction was deemed completed‚ the product was isolated and purified by ether extraction‚ aqueous extraction and evaporation. To determine how sodium hypochlorite acts as

protein consists of two sites: a constant region (C) and a variable (V) region. In the constant region‚ the amino acid sequences remain similar to another antigen receptor from another B cell. What determines the main difference in targeting specific types pathogen for each B cell is the variable region. A variable region of an antigen receptor from one B cell has completely different amino acid sequencing than the variable region of another antigen receptor from another B cell. Thus‚ the variable region

Abscisic Acid and Stomatal Closure Abscisic acid is a single compound unlike the auxins‚ gibberellins‚ and cytokinins. It was called "abscisin II" originally because it was thought to play a major role in abscission of fruits. Though ABA generally is thought to play mostly inhibitory roles‚ it has many promoting functions as well. In 1963‚ abscisic acid was first identified and characterized by Frederick Addicott and his associates. They were studying compounds responsible for the abscission

understand the experiments ahead of time; no more reading should be done during lab session. If you do not do this‚ you will be unable to plan and use your time efficiently. There are several lab techniques that you need to read on your own for each lab session for example distillation‚ extraction‚ crystallization etc. They are self-explanatory and if you are unclear about something always consult the lecturer. Students must write/draw a brief outline/flowchart of the procedure of the experiment before coming

____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ______ This lab was basically about finding the percentage of acetylsalicylic acid in an aspirin tablet. First‚ the base was created‚ which was made out of 1.00 g of NaOH and D-water. Then the buret was attached to the clamp on the ring stand and the base was poured into the buret. After that‚ one by one‚ an aspirin tablet was dropped

Application of lactic acid bacteria There are four major categories for the current uses and applications of LAB: food‚ cosmetic‚ pharmaceutical‚ and chemical applications. In food industry Recent years the interest increased in using LAB by using bacteriocin-like inhibitory substances (BLIS) because of their potential use as a natural antimicrobial agent to enhance the food safety of food products and increase the nutritional values of the food. Foods that fermented by LAB such as cheese

Investigating How Concentration of Acid Affects the Reaction Between Calcium Carbonate and Hydrochloric Acid Introduction ============ According to the collision theory temperature‚ concentration‚ surface area and catalysts all affect rates of reaction as shown in the diagrams below. Increasing any of these should increase the number of collisions and so increase the reaction rate up to an optimum point. Increasing the temperature causes the particles to collide with more

Exercise 10: Acid/Base Balance Worksheet Respiratory Acidosis and Alkalosis Activity 1: Normal Breathing 1. At 20 seconds‚ pH = 7.38 2. At 40 seconds‚ pH = 7.38 3. At 60 seconds‚ pH = 7.38 4. Did the pH level of the blood change at all during normal breathing? If so‚ how? No. 5. Was the pH level always within the “normal” range for the human body? Yes. 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No. Activity 2a: Hyperventilation
