Acids

working with very impure benzoic acid. The benzoic acid we were given was made by the 102 chemistry students, meaning that it wasn’t properly made. Students have said that they were rushed and weren’t able to take their time to filter the solid out of the solution. We had to do this for our 102 lab, and I know that our class was being rushed, and it didn’t help that this was the first time working with a funnel filtration. Working with a possible impure benzoic acid is an important thing to note…

Organic Acids An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO2OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak. In general, organic acids are weak acids and do not dissociate completely in water, whereas the strong mineral acids do. Lower molecular mass organic acids such…

time. One of the disorders that can be seen if the homeostasis fails to occur is the acid-base balance. For a person to be in a good health, the maintenance of acid and base should be balanced in the body which is an essential function of the body in the biological process. The most important aspect in the prevention…

pathogens and microorganisms may be present in pools that aren’t treated properly and can result in harmful side effects like swimmers ear or diarrhoea. Disinfectants are used to treat pools and chlorine is by far the most commonly used. Hypochlorous acid (HOCl) is the substance that sanitises these swimming pools (De La Matter, 2012). If kept within specified pH parameters then the system works well however there are many stressors of the backyard pool system. This includes variations in pH…

1-pyrenehexanoic acid was used as the 5-carbon linker and fluorescent component of the target molecule "PYRET-5". This molecule was purchased pure along with the sugar Trehalose, the molecule to which the pyrene was to be attached. Other reactants and solvents include HATU, HBTU, N, N-Diisopropylethylamine (DIPEA), sodium azide, Dimethylformamide (DMF), and Diphenyl phosphoryl chloride and were bought pure or used as received. All reactions were run at room temperature (298.15 K) and standard…

percentage amounts of ethanol in them; Listerine, Terra Fresca Wine and the last is a mixture of ethanol and water that was made by me. The three different methods compared are the redox titration method which involves the oxidation of ethanol to ethanoic acid and then titrating the residue with sodium thiosulfate, which would then be used to calculate the number of moles of ethanol present in the original sample. The method of distillation involves heating the samples to the boiling point of…

Experimental Design Aim 1: Determine the amino acid sensing specificity of folliculin. Since folliculin’s novel amino acid sensing function discovery, I plan to further understand whether FLCN specifically senses a certain amino acid and if this level of detection is enough to elicit an mTORC1 response. 1.1. Determine if folliculin’s novel molecular function in amino acid sensing is triggered by glutamine. mTORC1 activation by amino acids requires FLCN where its lysosomal residence during…

Introduction: Acids and bases are often described using the Bronsted-Lowry theory which states that acids are proton donors, while bases are proton acceptors (Thorne, 78). This means that an acid has additional H+ ion(s) that can be given, whereas a base lacks these ions and will accept them. Acids and bases can further classified as strong or weak. A weak acid, such as HF, will not ionize completely, meaning that only some of the H+ ions will be lost. A strong acid will however, will release…

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…

Acid Rain: Pros and Cons Acid Rain. Acid Rain is regular rain fallen from the clouds then made sufficiently acidic by atmospheric pollution. This is created by the process of burning fossil fuels, they contain sulfur and nitrogen oxides, which combine with atmospheric water to form acids. When people hear the words “acid rain” they immediately think about the horrors of it. Few people think about the positive things that acid rain can bring to us. With the evidence given, both sides could be…
