    had 3 reagents (Biuret’s, Lugol’s ,and Benedict’s). We had two different experiments, the first experiment was to get qualitative data. The second was to get quantitative date. The first experiment we tested each supplement with each reagent and also a positive and negative control for each supplement. We had a total of 15 test tubes. We would observe the color of each supplement and the reagents. We recorded the color of each solution and compared them…

    Introduction: Organic Molecules are the chemicals of life produced by living organisms. They contain carbon and hydrogen linked together in long chains, with carbon as the backbone. Three focal organic molecules are carbohydrates, proteins, and lipids. All living organisms need these organic molecules to survive. Carbohydrates are utilized for transporting and storing energy in animals and plants. The number of sugar molecules present determines the prefix for the carbohydrate. A monosaccharide…

    reactions of aldehydes and ketones. This was done to determine how they react when different reagents are used. Different carbonyl compounds were used with two unknowns. These compounds were then tested as to how they react using Tollen’s reagent, Iodoform test and Jones reagent test. Tollen’s reagent test is known for forming silver mirror precipitate…

    decalcifier are used for urgency case to accelerate the speed of decalcifier. For example, hydrochloric acid (HCl) is strong acid which act as rapid decalcifier with extremely low pH. It can rapidly removed inorganic calcium from the bone. Some chelating reagent like EDTA (at pH 7.0 - 7.4) is neutral hence it requires longer time to carry out the process. 2. Degree of mineralization Some of the sample like mucopolysaccharides in new bone, calcifying cartilage or glycogen in some early…

    Grignard reagent. Bromobenzene, magnesium turnings, and anhydrous ether were needed to form the Grignard reagent. To synthesize the reagent, react the reagent with methyl benzoate to form a tertiary alcohol. The objective of the Grignard Reaction lab was to obtain the actual yield of the product, to calculate theoretical and percent yield of the product, and to record the melting point of the product. Background The Grignard reaction is a reaction that form alcohols. The Grignard reagent is…

    focus and a good understanding of the procedures, which were, along with the materials, very detailed. With this being said, because most of the materials had similar names, it was important for students to not manipulate the lab by mixing up the reagents, which would completely ruin the experiment. The important factors that influenced the success of this experiment included the following: 1) 100% transfer, 2) 100% digestion, 3) controlling the amount of bacteria and metals absorbed from the…

    universally referred to as lime water or slaked lime is formed by reacting hydrated lime (calcium oxide, CaO) with water (H2O)[1] CaO (s) + H2O (l) ⇌ Ca(OH)2 (aq) (ΔHr = −63.7 kJ/mol of CaO) Calcium hydroxide is an economically favorable alkaline reagent to neutralize acid as it yields 2 moles of (OH)2 for every 1 mole of Ca(OH)2 (which is slightly soluble in water) when compared to sodium hydroxide [1] and it may separate from the solution ‘constant agitation must be done to prevent the…
