Experiment 4 Synthesis of Salicylic Acid Introduction Throughout history‚ botanical extracts have been used as medicines. Approximately 30% of all medicines have a plant origin. This number increases to 60% if you consider medicines that at one time were derived from plants‚ but have been synthesized in the laboratory. Salicylic acid is a white crystalline compound that can be isolated from the bark of birch trees. Since it is a valuable substance that can be isolated from nature‚ it is called

Ethanoic Acid Advantages: Ethanoic acid is non-toxic and is a weak acid‚ meaning it will not do any damage to most surfaces as it does not corrode or bind to other metals‚ therefore can be easily removed through washing or rinsing it. Disadvantages: Ethanoic Acid is the slowest de-scaler of the three acids‚ and is therefore the least effective. It also may cause an unpleasant smell‚ and can have a negative effect on the taste of coffee meaning one would need to spend longer time rinsing and cleaning

butanols with hydrobromic acid. Before the lab began we discussed and proposed mechanisms. (see “Mechanisms”) To begin this experiment we calculated how much of each material we were going to be using‚ and the numbers we chose to use differed from our reference text slightly. We used 6.5 mL of our assigned butanol and only 4 mL of sulfuric acid. Going back to our reaction mechanisms‚ we were looking at SN1 and SN2 reactions‚ so we of course used the hydrobromic acid as our acid catalyst which would be

An Investigation into the Factors Affecting the Rate of the Reaction between Calcium Carbonate and Hydrochloric Acid A chemical reaction is the process by which atoms or groups of atoms are redistributed‚ resulting in a change in the molecular composition of substances. The reaction rate is how quickly a reaction occurs and this can be affected by four different factors: ¡¤ changing the surface area of any solids involved ¡¤ changing the concentration of reactants in solution ¡¤ changing the temperature

Distinguished ladies and gentlemen. Acid rain is becoming a widespread problem around the world. The amount of acid in rain has dramatically increased in the past decade in certain areas like America and Europe by 70%. How is it caused? It is formed by the chemicals in the process of burning fossil fuels mixing with the moisture in the Earth’s atmosphere. Acid rain come in two forms‚ wet and dry. Dry deposition‚ a more accurate term for acid rain‚ can appear to be snow‚ hail or other dry particles

adopting new technologies and are using feed acidifiers for supplementing the diets of animals. The market value of propionic acid as a feed acidifier was the highest in 2012‚ and is projected to grow with the increasing demand for feed acidifiers in the livestock industry. The benefits of feed acidifiers are leading the market demand in the feed industry. The fumaric acid market is comparatively small and is projected to grow at a CAGR of 5.8% from 2013 to 2018. The feed acidifiers market is projected
