Strong acid

of around eight, or in other words the endpoint of a solution. It also allows us to see a physical change, thus resulting in a more accurate measure of how much was titrated. Citric acid is a weak acid, making it best titrated by using a strong base, such as sodium hydroxide. The combination of a weak acid and a strong base would result in an endpoint that corresponds to the range of phenolphthalein indicator approximately a pH of eight. Image A Phenolphthalein is composed of C14H20O4, as shown…

buffer solutions to sustain the structure and activity of biological components such as DNA, RNA, proteins, carbohydrates, and lipids. Buffer solutions are remarkably resistant to pH changes and generally consist of a weak acid and its conjugate base or a weak base and its conjugate acid. In the laboratory, artificially made buffers are often used to help maintain a biological system at the proper pH. A laboratory buffer should be inert in the system being studied. For example, Tris buffer is…

Introduction Acid-base titrations are used to calculate properties of an acid or a base by titrating them with a strong Acid or base. In a titration, certain amount of volume of one substance usually a strong acid or base, a titrant, is added to another substance, an acid or base of some kind, until a change in properties are observed. Strong acids and bases are used because they allow the neutralization reaction between the acid and base into salt to go to completion. By titrating an unknown…

Soap and Detergent Soap and Detergent are the cornerstones of human cleanliness. Soap is, “a substance used with water for washing and cleaning, made of a compound of natural oils or fats with sodium hydroxide or another strong alkali, and typically having perfume and coloring added”( Soap 2018 ). Detergent is, “ a water-soluble cleansing agent that combines with impurities and dirt to make them more soluble and differs from soap in not forming a scum with the salts in hard water” ( Detergent…

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…

on it which would have been removed with the stick. It is less clear why the benzoic acid was overproduced. Some of the organic layer may have been drawn off with it, but the vacuum filtration should have left only the benzoic acid. There could have been an error in weighing the filter paper before the procedure. There also could have been contaminants in the basic extract, causing more than just the benzoic acid to be filtrated. There is also the chance that too much starting material was…

four the acid rain and tap water seeds were alike. The seeds were round and tan. On day two the seed coat became squishy. On day three test one seeds two and three of the acid rain and water began to sprout roots, and all of the seeds in test two and three began to sprout. Seeds one, two, and three in the acid rain test one group’s roots began to curl on day four and the stem was just barely visible in seed one. The water seeds in test one, two and three the stem became visible. The acid rain…

acidity they are tasting. Acids and bases can usually be defined by your senses. For example, edible acids usually have a sour taste(4). Bases are more bitter-tasting and unstable(4). But, your senses are not the only ways you could detect acids. Sometimes you have to use measurements like the pH scale to detect if a substance is a acid or a base. Since, acids and bases surround us, it is important know information about them and how to detect them. Before we start measuring acid we have to…

oxygen3. Serratia Marcescens is a gram negative bacterium. Gram negative bacteria have a thin cell of a single layer of peptidoglycan that is enclosed by an outer membrane. The outer membrane is surrounded by special phospholipids composed of fatty acids called lipopolysaccharides that are attached to a glucosamine…

people take to help with an imbalance of the pH of their stomach acid because it neutralizes the gastric acid present (Antacids | Drugs.com). Although the is not just one brand of antacid that is available to people, and most people want to take the best antacid that will help with their acid imbalance. In our lab, we were given the question of which antacid out of the antacids provided to us was the “best” at neutralizing stomach acid. To answer that question me must first establish what makes…
