Results and Discussion A. Diffusion of selected plant pigments In conducting the diffusion of 4 different kinds of treatments (distilled water, distilled water placed in boiling bath, vegetable oil, heated vegetable oil), the researchers made use of the atsuete and sugar beets. The different kinds of treatments determined how the temperature will affect the color intensity of the atsuete and sugar beets. There were 4 test tubes used in each atsuete and sugar beets with each having a…

Abstract: Catalase is an iron porphyrin enzyme present in high concentrations in humans and animals liver tissues. It is a peroxisomal enzyme that is responsible for destruction of toxic H2O2 released during certain metabolic processes.The activity of catalase can be determined by measuring the decrease in H2O2 concentration which is the substrate. Introduction: An enzyme is a large protein that acts as a biological catalyst which changes the rate of a reaction. It provides an active site…

Alkaline hydrolysis Alkaline hydrolysis is a simple process in which the protein is solubilized by heating followed by the addition of calcium, sodium or potassium hydroxide as alkaline agents and maintaining the temperature at a range between 25-55 °C (Pasupuleti & Braun, 2010). During alkaline hydrolysis of proteins, some amino acids like serine and threonine are damaged during alkaline hydrolysis, however, tryptophan remains intact. Also, this process causes racemization of amino acids, by…

The zeolite XRD analysis result showed that it is 100% Clinoptilolite ─ Ca with the chemical formula Si29.04Al6.96O96.40Na1.92Ca1.57Ba0.32K0.56Mg0.72. Particle size distribution and Zeta potential for minerals have been carried out using Zeta sizer nano series (Nano ZS), Malvern, UK - Size range (nm):0.6:6000 nm and Zeta potential range (mV): (-200:200 mV) and analysis results are presented in Table 3. They The minerals were applied before planting in two separate rates ≈ 595.24 and 1190.48 5…

all foods. zinc is a bluish-white shiny metal if it is in pure form. Zinc has many uses in industry in Metallic form. Alloys such as brass and bronze are form by mixing of metallic zinc with other metals. Zinc form salts as it combines with other chemicals. In nature, most zinc ore is found as the salt of zinc sulfide. Sphalerite (ZnS) a element is found in association with other base metals such as copper and lead in ores. Sphalerite ore contain 60-62% zinc. It is the most heavily mined…

The goal of this lab was to conduct the reaction of 2-methyl-2-butanol with HCl to form 2-chloro-2-methylbutane, and to understand Sn1 and Sn2 reactions, in terms of how they are different and why one is more likely to happen over the other. The OH group in 2-methl-2-butanol is attached to a tertiary Carbon, meaning the reaction should occur via Sn1, a two-step reaction, and Cl should replace the OH group, to form a tertiary halide. HCl was added to 2-methyl-2-butanol and then several…

Number: 13335535 Lab Partner’s Name: Ifeoma Agu Demonstrator: Maria Inorganic Chemistry Experiment 3: The Identification of Unknown Samples Objectives The experiments were carried out in order to identify 15 samples, through their physical and chemical properties. Theory A precipitation reaction is one which produces an insoluble salt as product. An example would be; Ca(NO3)2 + H2SO4 = CaSO4 + 2HNO3 The calcium salt is insoluble. Precipitation reactions could be used in this experiment to…

The purpose of this experiment was to learn techniques to determine the freezing point of a pure benzophenone, a solvent. Furthermore, methods for determining the freezing point depression in relation to the solute, cyclohexanone, concentration were employed in addition to learning what molality is and how it related to the colligative properties being studied. These objectives were achieved by melting both pure benzophenone and benzophenone/cyclohexanone solutions (two solutions with…

[Chemical Engineering Lab Practice 4] EXTRACTION OF BENZOIC ACID Candidate’s Name: Raajeswari A/P Radahakrishnan Student ID: SCM-023562 Group Member’s Name: Angela A/P Gunasegaran Shubashinee A/P Murugan Lecturer/ Supervisor: Ms Nazlina & Dr Ong Chi Siang Date of Submission: 13 October 2015 1.0 ABSTRACT This experiment is about extraction of benzoic acid from kerosene by water droplets that was conducted on 6 October 2015 with few group of students. The main purpose of…

equations helps us mathematically see what is happing during the reaction besides performing and watching it occur. Being able to identify the limiting reagent, products produce, and solve for molarity is key to chemical analysis. Performing the experiment is just half of the equation in chemical analysis. This lab did not have many safety precautions except there was an open flame…
