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…

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…

of how this relates to the biological studies of biology and to the advantage of humans. Hydrochloric acid combined with water will not a make good buffer system. Hydrochloric acid is a strong acid that will not coexist with any other base in equilibrium. When hydrochloric acid drops…

The list of errors start from the beginning of the experiment. Although the numbers seem to be close to the actual values, there is still room for error with the numbers. What the class noticed first is that we could have been working with very impure benzoic acid. The benzoic acid we were given was made by the 102 chemistry students, meaning that it wasn’t properly made. Students have said that they were rushed and weren’t able to take their time to filter the solid out of the solution. We had…

Question 1: pH can be described as a measure of acidity or basicity (Alkalinity) of a solution. It is exactly equal in amount to the negative log of the concentration of hydronium(H3O+) ions. Due to the negative log relationship, increased hydronium ions transform to lower pH. When we add it to water, an acid releases hydrogen ion. Hydrogen ions in water unite with the water molecules to form hydronium ions, thereby lowering the pH and increasing the acidity of water. Water exposed to air is…
