Win Metal Company: Single Supplier Solutions for Lack of Sulfuric Acid

controversy? Explain why. 1. Single supplier Solutions for lack of sulphuric acid: -‘’Sulphric acid is a material used in the production of viscose fibres, so in addition to the environmental effect, the recovery of sulphric acid will entail considerable savings. WSA plants can eliminate hydrogen sulphide and carbon disulphide contained in the off-gases by converting these sulphur compounds into sulphuric acid. 2. Human resources mgt- Immediately passing legislation that will bring a...

Experiment :Alkanes&Alkenes:Combustion and action of sulphuric acid

Experiment 1 :Alkanes&Alkenes:Combustion and action of sulphuric acid. Introduction In the study of organic chemistry, the organic compounds which are made up of carbon and hydrogen are called hydrocarbons. They can be gases as, propane, they can be liquids, for example, benzene, or they can be low-melting solids and waxes, for example, polystyrene. There are four classifications of hydrocarbons; saturated hydrocarbons or alkanes, unsaturated hydrocarbons or alkenes and alkynes, cycloalkanes,...

Spectroscopy Laboratory Quinine in Tonic Water with Fluorescence

solution of Nitric Acid, 10 ppm standard of quinine sulfate, distilled water, Tonic Water, and 1M solution of Sulfuric Acid. The equipment required was a 500 mL volumetric flask, a 50 mL Volumetric Flask, 4 100mL volumetric flasks, a 250 mL volumetric flask, pipettes, cuvettes, and the fluorescence spectrophotometer. The first part of this experiment consisted of meticulously washing the glassware. We did this with a 1:1 dilution of Nitric Acid, rinsing first with the acid and then with distilled...

Experiment to Investigate the Effect of Concentration on Rate of Reaction

voltaic cell. Hypothesis My hypothesis is that the greater the concentration of sulfuric acid the bigger the current of the voltaic cell. In a voltaic cell, chemical energy is concerted to electrical though the oxidation and reduction happen on the electrodes. Current will not flow through pure water. There must be electrolytes dissolved in it before electricity can pass through it. When the concentration of sulfuric acid is increased, the number of ions is increased. There will be more ion carrying...

Lab 5:

nucleophile in this lab is generated from an aqueous solution of sodium bromide. The sulfuric acid acts as a catalyst in converting the OH functional group of butanol, to a better leaving group (water). The by-products for this lab are 1-butene, di-n-butyl ether, and the starting alcohol (butanol). Any by-products are removed by extraction using concentrated sulfuric acid. The product can be removed from sulfuric acid, since it does not mix with H2SO4 and will remain as a separate layer. Procedure:...

Exp 1

Introduction : Copper(II) sulphate, is a type of salt which it is formed by combining both copper ion and sulphate ion through the experiment of double displacement between dilute sulphuric acid , and copper(II) carbonate , . Through this process, the copper ion will displace the hydrogen ion as it is more electropositive and sulphate ion will displace carbonate ion as it is more electronegative. The resulting copper (II) sulphate solution when cooled can easily crystalize...

Synthesis of 1-Bromobutane from 1-Butanol

Laboratory; John R. Ganson Ph. D, Revised 2011 by Alfredo Mellace Ph. D www.Aldrich.com Purpose: To synthesize 1-bromobutane from 1-butanol via SN2 reaction. Alcohols are converted into the alkyl halides adding an aqueous solution sodium bromide. The sulfuric acid acts as a catalyst in converting the OH functional group of butanol, to a better leaving group. In order for this reaction to synthesis 1-Bromobutane, four major methods refluxing, simple distillation, separation, and gravity filtration needs...
