Figure 2 Figure 3 Figure 1 show the crystallisation reaction when the saturated sodium chloride solution was added to the cool reaction mixture. The salt of p-Toluenesulphonic acid started forming. Figure 2 show the wet crystal after the precipitated salt was being filtered by suction. The wet crystal was light purple in colour. Figure 3 show the end product after drying the wet crystal at 105°C in the drying cabinet (oven)

Acid-Base Balance and Fluids and Electrolytes Student’s Name Institutional Affiliation Date Due Respiratory Acidosis Respiratory acidosis refers to a medical defect in which hypoventilation occurs leading to increased concentration of carbon dioxide in the blood and decreased level of pH. Decreased pH in the blood is generally known as acidosis. The body cells continuously respire and release carbon dioxide. The lungs may fail to efficiently expel the CO2. This condition is known as alveolar

Abandoned Acid Mine Drainage at Shoup’s Run Introduction Acid mine drainage (AMD) is an industrial waste which is the result of the extraction process of the mineral coal from the ground. It causes widespread pollution in the streams above and below the coals fields. AMD is caused when water flows through sulfur-bearing materials forming acidic solutions. It is formed when pyrite (FeS2)‚ an iron sulfide‚ is exposed and then reacts with air (O2) and water (H2O) to form sulfuric acid. 2FeS2 (s)

Thermochemistry (((CLASS INFORMATION)) INTRODUCTION Thermal chemistry was intended to display that chemical reaction and phase changes involve energy. The energy of heat was presented when a change in temperature difference was evaluated. Chemical reactions in a calorimeter were used to determine the amount of heat produced by a reaction. Reactions that absorb heat were noted as endothermic‚ and reactions that release heat were noted as exothermic

1. Mechanism of oxidation process In an oxidation process of silicon that usually takes place at very high temperature (thermal oxidation)‚ silicon (Si) reacts with either water vapor (H20) or oxygen (O2) to form silicon dioxide‚SiO2 on the silicon surface. The reaction is represented by following equations: Dry oxidation: Si + O2 → SiO2 Wet oxidation: Si + 2H2O → SiO2 + 2H2 The oxidation process can be implemented through diffusion

The purpose of this experiment was to study the effect acid rain has on seed germination and after performing this experiment is can be concluded that acid rain has a negative effect on seed germination. When seeds are soaked in an acidic solution the process of germination slows. Acidic solutions‚ while do slow growth of a seed‚ they do not kill the seed. A seed can be dormant for a majority of its lifespan‚ seeds watered with acid solutions stayed in a dormant condition. For example‚ trial three

DEFINITIONS OF OXIDATION AND REDUCTION (REDOX) This page looks at the various definitions of oxidation and reduction (redox) in terms of the transfer of oxygen‚ hydrogen and electrons. It also explains the terms oxidising agent and reducing agent. Oxidation and reduction in terms of oxygen transfer Definitions • Oxidation is gain of oxygen. • Reduction is loss of oxygen. For example‚ in the extraction of iron from its ore: [pic] Because both reduction and oxidation are going on side-by-side
