Determination of the Rate Constant for a Chemical Reaction Department of Chemistry Abstract This experiment was performed to determine the rate constant k‚ for hydrolysis of tertiary butyl chloride to tertiary butanol. The solvent system for this reaction is 45% isopropyl alcohol and 55% water. The rate of hydrolysis of t-butyl chloride is measured by the decrease in the concentration of this reagent with time. The rate of decomposition of t-butyl chloride must be equal to the rate of formation

catalysts‚ photochemicals‚ ceramics‚ food stuffs etc. Recent applications include crystalline materials for electronic devices‚ speciality applications such as healthcare products [1‚2] (Zauner‚ 1999; Jones et al.‚ 2005). One of the important challenges in the field of industrial crystallization is to match the changing and growing product requirements across all industrial sectors (pharmaceutical‚ chemical‚ process industries‚ food‚ nutrition and agro-chemistry) by controlling the crystal morphology‚

Exp. 2A-D Solubility (pp.13-20) In this experiment‚ I will be determining/investigating the solubility of different solvents‚ or more precisely‚ the extent to which a substance is soluble or insoluble (Part A and B). Another goal of this experiment will be determining miscible (liquids that will mix homogeneously) and immiscible (liquids that do not mix homogeneously) parts in liquids (Part C). Part D of the experiment will be looking at solubility as well‚ the solubility of organic acids and

The main purpose of this lab is to experiment the molecular polarity on the solubility of solutes in variates of solvents and helped us to determine the polarity of the unknown solute. In this lab‚ we observed the effects of adding polar liquid solutes to non-polar liquid solvents. Materials used: Safety goggles 3 graduated cylinders ethanol‚C2H5OH solid iodine‚ I2 glycerol‚ C3H5(OH)3 water 10 rubber stoppers 10 test tubes kerosene ammonium chloride

Solubility refers to the maximum amount of solute that dissolves in a given amount of solvent at a particular temperature Factors Affecting Solubility 1. Effect of Temperature For some substances to dissolve in a given solvent‚ heat is absorbed. The reaction is endothermic. In this case‚ an increase in temperature increases solubility. For some substances‚ heat is released when they dissolve in a given solvent. The reaction is called exothermic. In this case‚ an increase in temperature
