Task 3: Tests for Anions: An Anion is an atom which is negatively charged therefore indicating a larger amount of electrons than proteins. Overall the tests for anions were mainly conclusive however 6 out of 8 of the anions we were testing for could only be determined from one specific result for example if a black precipitate formed following the tests the substance is therefore a sulphide however the same result would also show the presence of carbonate and hydrogen carbonate this therefore

Discussion/Conclusion In this experiment‚ t-pentyl chloride was synthesis by reacting concentrated hydrochloric acid using nucleophilic substitution sn1. In the substitution reaction the Hydrogen in HCl protonated the alcohol group in t-pentyl alcohol and turned it to a good leaving group (H2O). a tertiary carbon cation was formed. a nucleophilic attach of the negative Cl- attacked the carbon cation forming t-pentyl chloride [7]. As the reaction proceeded‚ extraction and distillation techniques

Title: Flame Test Aim: To determine the cation in each of the unknown substance X‚ Y and Z by observing the flame colour of different metal compounds. Introduction: A distinctive feature of many s-block metals is their ability to produce flame colours. At temperature of a Bunsen flame‚ a compound will decompose to give gaseous atoms of its constituent elements. When an electron in the gaseous atom absorbs energy from the flame‚ it will move from an orbital with lower energy to

Discussion Questions 1. Why do different metals have different characteristic flame test colours? The photons emitted during the test precisely match the quantum energy difference between the excited state and the ground state. For different elements the spacing between the ground state and the higher energy levels is different. So different elements have different flame test colours. 2. Most salts contain a metal and a non-metal. Look at the compounds we tested and determine whether it is

June 2007 Test Under Simulated LSAT Conditions One important way to prepare for the LSAT is to simulate the day of the test by taking a practice test under actual time constraints. Taking a practice test under timed conditions helps you to estimate the amount of time you can afford to spend on each question in a section and to determine the question types on which you may need additional practice. Since the LSAT is a timed test‚ it is important to use your allotted time wisely. During the test‚ you may

come up with a hypothesis‚ test our experiment with the new independent variable‚ and confirm or reject our hypothesis. We picked experiment 2. In this experiment‚ water was combined with baking soda. Then the temperature was taken‚ and finally calcium chloride was added‚ which formed a chemical reaction. Our lab question was how does the amount of calcium chloride affect the temperature of the product? We chose our independant variable to be the amount of calcium chloride added to the water/baking

IB Chemistry Lab Report Design Example— Effect of Temperature on Solubility of Potassium Chloride in Water Research question How does temperature affect the solubility of potassium chloride in water? Hypothesis As the temperature of water increases‚ the particles of solid Potassium chloride‚ KCl‚ which are absorbing energy from its surrounding‚ start moving more easily between the solution and its solid state because. According to the second law of thermodynamics‚ the particles will
