INTRODUCTION 1.1What is an acid-base titration? An acid –base titration is the determination of the concentration of an acid or base by neutralizing the acid or base with an acid or base of known concentration. An acid-base titration is the analysis of the concentration of acids and bases; through this process an acid or base of known concentration neutralizes an acid or base of unknown concentration. The neutralization of an acid or base in acid-base titration can be measured with either a…

The % relative standard deviation (% RSD) was found to be below 5 % for all the four analytes in system precision and below 6 % in method precision. The data as shown in Table 3.4.3.3.3 and 3.4.3.3.4. LOD values observed for Hydrazine carbamate and Hydrazone carbamate were 0.0018 µg per mL and 0.00092 µg per mL respectively. The LOD value observed for both 1-Hydroxy benzotriazole and 2R, 3S Chlorohydrine hydrochloride were 0.0019 µg per mL. The LOQ values observed for all four analytes were…

Acid Base Balance Study Guide Definition: The body’s ability to regulate and compensate for variances of the acidity or alkalinity of body fluids through mechanisms in the brain, kidneys, lungs, and buffering system. Concept Key Terms: • Acid: any substance that has a pH less than 7.0 • Acidosis: the condition of having too much acid build up in body fluids, below 7.35 • Alkalosis: the condition of having too much alkaline build up in body fluids, above 7.45 • Anion: a negatively charge…

In this project the aim is to determine the equilibrium constant (Kc) of a weak base when it reacts with a weak acid. The chemicals I wish to determine the equilibrium constant for are, Ethanoic acid (CH3COOH) and Propanol (C3H7OH). To accomplish this, the first question we must ask is, “what is an equilibrium constant and how is it determined”? There are 2 different types of equilibrium. The first, and the type we shall be using is known as homogeneous equilibrium which has everything present…

Because there are 5 things simultaneously present, 5 equations must be made. Two for the equilibrium constants, one mass balance equation for all A containing material and one for Na+, and 1 charge balancing equation as shown in the appendix. Since we are looking for the KA we need the equation in the form of KA = [H3O+][A-]/[HA]. Therefore the 5 equations…

Symmetry Writing Exercise Paragraph 1 The research paper written by J. Haines, O. Cambon and S. Hull aims to understand how Iron III phosphate (FEPO4) behaves under high temperatures and at which temperature would we start to observe structural transition of Iron III phosphate. As found by the researchers, the temperature where one is able to witness a structural change of Iron III phosphate, a transition from α-β would be at the temperature of 980K. As the researchers have highlighted, there…

This can also be seen by the value of the rate constants where k1 k2. Additionally the process of phenol decomposition by direct ozonation is different than that of indirect ozonation. Degradation of phenol by OH radicals favors the formation of aromatic by products, following the formation of organic…

results are reported in Table 1. Table 1: Effect of pH [Basic fuchsin] = 0.8 × 10-5 M Light intensity = 60.0 mW cm-2 CuO/Al2O3 = 0.12 g pH Rate constant (k) × 105 (sec-1) 4.0 4.40 4.5 5.68…

Proteins are known as the building blocks of cells in all living organisms. Many hormones are made up of proteins and the digestive system, immune system and blood replies on proteins. Therefore, protein is an essential part of healthy diet, and integral to development of the body. The purpose of performing this lab is to analyzing the activity of TEM-1 B-lactamase and how it reacts with high temperatures, chaotropic salts, detergents and pH values. INTRODUCTION: Primary protein structure is…

Paragraph 1 The crystal chemical relationship between quartz (SiO2) and FePO4 can be studied by putting them under a temperature range of 294K to 1073K in an attempt to study the evolution of their structures. In doing so, we would able to examine the other quartz homeotypes that emerge during high temperatures and known to show a-b transitions. This study of quartz homeotypes were essential because the new information that was gathered would aid greatly in the creation of new products and more…
