Sulfuric acid

Safety One of the main safety issues with the experiment involves the chemicals used in the reaction. The salicylic acid can cause irritation to the skin and eyes, cause cough or sore throat if inhaled, and cause nausea, vomiting, or ear ringing if ingested. Salicylic acid is also combustible and finely dispersed particles in air can be explosive (CDC Salicylic Acid, 2014). Acetic anhydride is corrosive and can cause severe irritation and burns to the eyes and skin, which can even lead to a skin allergy. Acetic anhydride, if inhaled, can cause cough, laboured breathing, and sore throat. If ingested, it can cause abdominal pain, a burning sensation, and shock. It is a flammable liquid and above 49 °C may form flammable vapors (CDC Acetic Anhydride,…

The purpose of this lab was to perform the condensation of acetic acid with isopentyl alcohol in the presence of sulfuric acid. Isopentyl acetate was formed from this reaction and this compound has the distinct smell of bananas. This reaction is known as Fisher Esterification. From the final product, the final mass was used to calculate the percent yield. Finally, the IR spectrum was obtained from the final product in order to determine if the reaction went to completion or not. To a 5mL…

944 Kg of sulfuric acid to the environment and 8,929,868 Kg of sulphuric acid to air. The most that was recorded for the concentrations of sulfuric acid in air were 678 ug/m3 in London, 240ug/m3 in Los Angeles, and 50 ug/m3 in Ontario. 0.5 mg/m3 of pickling, electroplating, and other acid treatments occupational exposure to sulfuric acid occurs in the OSHA are allowed for the exposure limit which is 8 hours is 1mg/m3. Cost of the process Sulfuric acid have varied global…

Discussion The T-test from the class supported our hypothesis by showing that Sulfuric Acid diffused significantly faster than phenol red at both temperatures (Fig 1). We can say that our hypothesis for experiment one is supported under certain conditions. The rest of the data in our charts supports our hypothesis as well. However it is not well supported. The rest of the test results were inconsistent with the null hypothesis. The error bars from the class data show a possible cause of…

Chapter 6 Experimental Work ACETATE BY HPLC Method of Analysis Mobile phase: 0.025 mol/L (0.05N) sulfuric Acid. Using a volumetric pipette, add 3 ml of concentrated sulfuric acid to approx. 1500 ml water in 2 liter volumetric flask. Dilute volume with water. Standard Preparations: Accurately weigh 0.240g each std1 and std2 of sodium acetate tri-hydrate W.S. into 100 ml volumetric flask. Then dilute 25 ml to 50 ml with water. Sample Preparation: Dilute with water such that the…

the measurement was reduced down to 0.1cm3 then the ratio would be to 60:1 which is a great difference to the other ratios seen. The percentage for 1cm3 is 87.5%, 58% for 2cm3 and 42% for the 3cm3 cube which shows the amount of Sulfuric acid that was able to react within the Agar. When this reaction happened, the colour of the Agar cube changed from purple, to clear which can be seen in figures 1 and 2 as the colour has disappeared from the outside, heading inwards towards the centre. This…

The reaction between Propanone and iodine under acidic condition Aims To find the order of reaction with respect to propanone, iodine and sulfuric acid, thus proposing a rate equation. Find rate constant at various temperature and with the use of the Arrhenius equation, find the activation enthalpy of the reaction. General Method {For step by step guide of the experiment see preparation page} By using known concentration of aqueous iodine solution (0.000 moldm-3, 0.005 mol dm-3, 0.015…

back high in to the atmosphere into freezing temperatures (This is an updraft). The drop begins to fall again gaining more moisture and getting bigger. This happens over and over again until the drop is big enough to fall down to the surface as hail. So we know what rain is like on our planet. What is it like on other worlds? Let 's take a trip to the first stop in our adventure, the planet Venus. Venus is Earth 's twin. It closely resembles the size of our home. Venus is the hottest planet in…

for re-use. Some of these technologies generate liquid effluents, solid wastes, and air emissions during the regenerating process. The types of wastes, effluents, and wastes vary with the technology and processes used, and the environmental control methods [CEPA, 1994]. Liquid effluents are required additional treatments before they can be reused for cooling or discharged to a sewer system [CEPA, 1994]. Solid wastes generated from the regenerating process include various types of sludge (e.g.,…

While the list had a very large number of different materials that were located in the shop, I only will list the chemicals that would present an industrial health hazard to an employee using them and chemicals that are used in every battery repair. Since some repairs use different chemicals and different processes, I decided to narrow it down to a very basic battery repair that would be done at the Fairmont shop I visited. First would be sulfuric acid, which is used in the cells of the battery…
