Abstract In this experiment, the reaction kinetics of the hydrolysis of t-butyl chloride, (CH3)3CCl, was studied. The experiment was to determine the rate constant of the reaction, as well as the effects of solvent composition on the rate of reaction. A 50/50 V/V isopropanol/water solvent mixture was prepared and 1cm3 of (CH3)3CCl was added. At specific instances, aliquots of the reaction mixture were withdrawn and quenched with acetone. In addition, phenolphthalein was added as an indicator.
Purpose: The purpose of this lab is to titrate an unknown solid acid (KH2PO4) with a standardized sodium hydroxide solution. After recording and plotting the data, the acid’s equivalence point will be recorded once the color changes. Using the equivalence point, the halfway point will be calculated, which is used to determine the acid’s equilibrium constant. The acid’s calculated equilibrium constant will be compared with the acid’s established pKa value. Eventually using the NaOH and the acid’s consumed moles, the equivalent mass will be determined.
In this experiment, racemic 2-methylcyclohexanone was reduced using sodium borohydride as a nucleophile to give a diastereomeric mixture of cis and trans secondary alcohols. The products were analyzed for purity using IR spectroscopy and gas chromatography. 1.2 g of 2-methylcyclohexanone and 10 mL of methanol were combined in a flask and cooled in an ice bath. Two 100 mg portions of sodium borohydride were added to the flask and stirred. 5 mL of 3M sodium hydroxide, 5 mL of de-ionized water, and 15 mL of hexane were added to the reaction flask and stirred.
Introduction The goal of the experiment is to examine how the rate of reaction between Hydrochloric acid and Sodium thiosulphate is affected by altering the concentrations. The concentration of Sodium thiosulfate will be altered by adding deionised water and decreasing the amount of Sodium thiosulphate. Once the Sodium thiosulphate has been tested several times. The effect of concentration on the rate of reaction can be examined in this experiment. The chemical equation for this experiment is hydrochloric acid + sodium thiosulphate + deionised water (ranging from 25ml to 0ml in 5ml intervals) sodium chloride + deionised water (ranging from 25ml to 0ml in 5ml intervals) + sulphur dioxide + sulphur.
The Effect of Alkaseltzer Tablets on the Boiling Point of Water Zackary Zambrano Chemistry Honors Mrs.Gregor Period-3 10/5/16 Introduction Statement of Purpose: The purpose of this experiment is to see whether or not alkaseltzer tablets have an effect on the boiling point of 100 mL of water. The control is just water, the variable groups are 100 mL of water with one tablet, and 100 mL of water with two tablets. “What exactly is boiling? The technical definition is what occurs when the vapor pressure of a liquid is greater than or equal to the atmospheric pressure.”(Lopez,k) Simply put water, boils when enough energy is released to cause bubbles and then turn to vapor. When water begins to boil, the water will continue to boil at

Then using the radiation sensor to measure the thermal radiation (4 surfaces). Also take notes of the voltage across the cube (voltmeter). Then using the target thermistor resistance at temp of 125 ͦC, 120 ͦC, 115 ͦC etc. (use a fan to cool the leslies cube) Theory: Stefan-Boltzmann law is defined as J=ɛσT4 Where T= radiates energy with radiant heat flux σ= 5.67x10-8 Wm-2 K-4 ɛ= (0,1) the ɛ is equal to when 1 when the object is a black body. In this experiment we are using a sensor that is emitting radiation and we must take into account the corresponding
