EXPERIMENT 2: SYNTHESIS OF ORANGE II (2-NAFTHOL ORANGE OBJECTIVE 1. To produce dye based to the coupling of diazonium. 2. To understand the characteristic of dye orange II. INTRODUCTION The first dye was introduced by William Henry Perkin on 1856. It can be produced by the coupling of diazonium sulfanilic acid with nafthol in alkaline solution.. This was the common method used to produce dye nowadays. In this experiment‚ dye produced was the orange II. Azo compound is compound that contain

Chemistry Lab Report on standardization of acid and bases. Purpose: To prepare standardize solution of sodium hydroxide and to determine the concentration of unknown sulfuric acid solution. Data and Calculations: This experiment is divided into two parts (Part A and Part B). In the first part of experiment‚ the standardize solution of sodium hydroxide is prepared by titrating it with base Potassium hydrogen phthalate (KHP). The indicator Phenolphthalein is used to determine that whether titration

Flame test: AIM: To determine which part of the salt is responsible for the characteristics in the flame. HYPOTHESIS: If we introduce a metal salt in the blue flame of the Bunsen burner‚ then the colour given off by the flame is due to the metal part of the salt. METHOD: (1) With a heat proof mat under the Bunsen burner‚ turn the gas on and light up the Bunsen burner with matches. (2) Pour enough Hydrochloric acid into a beaker. (3) Using your wire‚ dip it into the beaker containing Hydrochloric

Introduction: The purpose behind (the first step in) this experiment is to show that similarly to week 1‚ the molarity of an acid or base in solution can be determined (so long as one value’s is known) using titration. In this case though‚ finding the molarity of the acid used in the reaction is then used to determine the percent of that acid in a vinegar solution and compared to the standard value for % acid present in vinegar. The second part of the experiment was to see if by titrating a solution

FDA Vinegar / Acetic Acid Analysis Objective- Determine the Acetic acid level contained within the vinegar sample Background- Per the FDA regulation which states that consumer vinegar may contain no less than four percent and no more than five percent Acetic Acid‚ we will determine the Acetic Acid content of a sample of the vinegar in question through titration. After standardization of our titrant‚ which in this case will be NaOH‚ we will use this along with the indicator Phenolphthalein

Chemistry (the etymology of the word has been much disputed)[1] is the science of matter and the changes it undergoes. The science of matter is also addressed by physics‚ but while physics takes a more general and fundamental approach‚ chemistry is more specialized‚ being concerned with the composition‚ behavior (or reaction)‚ structure‚ and properties of matter‚ as well as the changes it undergoes during chemical reactions.[2] It is a physical science which studies various substances‚ atoms‚ molecules
