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…

The concept of dynamic equilibrium can be understood using the properties of a titration of a strong base with a weak acid, including its equivalence point and half-equivalence point. The following equation demonstrates the dynamic equilibrium achieved when using a weak acid: The Ka value of a weak acid can be found experimentally using a pH meter along with the concept of equivalence point when titrating an acid and a base. One half of the weak acid has been titrated at the half-equivalence…

Have you ever heard about alkaline water? Do you really know what it is? When it comes to alkaline water, you should know this water is slightly basic. It has basic minerals, including magnesium, calcium and bicarbonate. All these compounds will bind to hydrogen ions in solution, making the water more basic. Moreover, this type of water refers to its pH level, which is a number that measures how alkaline a substance is on a scale of 0-14. For example, if something will have a pH level of 1, it…

weak acid. Furthermore, Equation 2 describes the equilibrium constant of a weak acid. On the other hand, Equation 3 and Equation 4 illustrate the chemical equation for the dissociation and equilibrium constant of a weak base. HA ↔ H+ + A-…………………………………………………. Equation 1 Ka=[H+][A-]/[HA]……………………………………………… Equation 2 BH+ + OH-↔ B + H2O………………………………………… Equation 3 Kb= [B+][OH-]/[BOH]…………………………………………. Equation 4 The equilibrium constants (Ka and Kb) are intrinsic properties of a particular…

The amount of time required for a chemical reaction to come to completion can vary tremendously depending on the reaction (Addison-Wesley, 2002). The speed at which any reaction proceeds can be defined as a reaction rate (J. Laidler, 2015). The rate of reaction can only be obtained experimentally, in order to yield a rate law. By conducting this experiment, it has the potential to harvest useful information regarding the understanding of rates of reaction. Understanding the rate of reactions is…

HCl has a high dissociation constant which means it releases all the hydrogen atoms when dissolved in water whereas, CH3COOH has a low dissociation constant which means it dissociates incompletely, releasing only some hydrogen when dissolved in water. Also, it was evident in the experiment where electricity was passes through the 0.1M of CH3COOH…

Throughout this acid, base and buffer lab, this will allow each individual to gain an enhanced sense of knowledge of how these different aqueous solutions work as a buffer system or how they are unable to perform as buffer system mixed with two solutions together. This can be identified through the colour change to measure pH behaviour in several aqueous solutions, therefore the different factors that will cause the change of pH. This will gain understanding of how this relates to the biological…
