This reactant can be used in certain reactions to produce valuable solutions for ophthalmologists. This product is going to waste‚ and our objective is to see if we can obtain a usable end product when reacting m-aminobenzoic acid with 2‚4-dinitrochlorobenzene. In order for this reaction to take place‚ we must verify that we can obtain

acidification is the build up of hydrogen ions(H+)‚ reducing the pH‚ therefore the soil becomes too acidic. The donor can be an acid‚ such as nitric acid and sulfuric acid.The addition of the acids can be due to acid rain and pollution. Many nitrogen compounds‚ which are added as fertilizer‚ also acidify soil over the long term because they produce nitrous and nitric acid when oxidized in the process of nitrification. Acidification also occurs when base cations such as calcium‚ magnesium‚ potassium

Background: Benzocaine | | C9H11NO2 | Reaction scheme for Fischer Esterification of p-aminobenzoic acid: Synthesis of Benzocaine.3 In 1890‚ a chemist named Ritsert‚ was the first to synthesis benzocaine and introduced it in the market in 1902. Benzocaine is a pain reliever and has many active over-the-counter ingredients. It is also used as a lubricant and topical anesthetic on intratracheal catheters and pharyngeal and nasal airways to obtund the pharynegeal and tracheal reflexesl.2 Sodium

The objective of this lab was to prepare n-butyl bromide or n-bromobutane‚ which is derived from an alcohol and an acid. In this case‚ n-butyl alcohol and sulfuric acid were the reagents. There were two methods of distillation that was involved in this experiment. The first was by reflux distillation‚ which is used to speed up a chemical reaction without having the reactants/ products evaporate or explode. Data Table 1 indicates the amount of each reagents that was prepared for the reflux apparatus

stir for five minutes in order to be sure that the end point is reached. Proper mixing of acid and antacid will allow results to be accurate. When hydrochloric acid is initially added into the solution‚ the Congo Red indicator will immediately detect the low pH of the acid and change to blue‚ but it is inaccurate because the acid has not reacted with the antacid yet. Stirring the solution will allow the acid and antacid to thoroughly mix together. As both reagents react with each other‚ the color

9.1 Sulphuric Acid Sulphuric Acid is Manufactured in Industry 1. Sulphuric acid‚ H2SO4 is manufactured in industry through Contact Process. 2. The raw materials used are sulphur‚ air and water 3. The Contact process consists of three stages. Stage 1: The production of sulphur dioxide This can be obtained by two methods: 1. Burning of sulphur in dry air in the furnace S + O SO2 2. Burning of metal sulphide such as zinc sulphide or iron(III) sulphide in dry air. 2ZnS

In this experiment set up‚ sulphamic acid was used‚ as it is a solid acid and be added dry‚ without any water‚ which is a reactant in this experiment equilibrium. Esterification is a slow and reversible reaction. The equation for the reaction between an acid RCOOH and an alcohol RẬᶦ can be the same or different;
