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

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

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
