The Various Types And Their Applications

| NaHCO₃ reacts with the hydrochloric acid by heating up violently, bubbling, dissolves, and new gas formation

Acids are a substance that has a pH less than 7. There are two different types of acid:

The SN1 mechanism leads to substitution products, and the E1 mechanism leads to formation of alkenes, therefore in this case, it is shown that this mechanism leads to a substitution of products since the Cl- ion is replacing the OH group by the addition of a strong acid (HCl). When the nucleophile

An acid is a substance which has an excess of H+ ions. Common characteristics of acids include tasting sour and reacting strongly with metals. The acid used in this lab was Hydrochloric Acid (HCl). A base is

In the 1990s, the effect of chloride on the acid-base balance was thoroughly studied as a physiochemical approach, called the Stewart approach. With the Stewart approach, chloride is a key determinant of the strong ion difference (SID), one of the three independent variables to determine the acid-base status (the two other independent variables are the partial pressure of carbon dioxide and the total weak acid concentration).

The product of this reaction is an aromatic molecule, which can be activating or deactivating. An aromatic ring with an oxygen sigma bonded to C1 and a methyl group is considered activating. This molecule is activating because the oxygen has two lone pairs of electrons surrounding it. In contrast, an aromatic ring with a carbon sigma bonded to an aldehyde is considered deactivating. This is due to the double bond of the oxygen to the carbon. Another observation seen in this reaction were emulsions. These were seen because water and HCl were added to the solution. Both serve as salts in this instance, as they both want to dissociate in both layers. In order to solve this issue and get the most product, sodium bicarbonate was added to the solution.

A very useful and common practice often used in routine physical exams is palpation. This technique, among its several uses, allows to estimate changes in the mechanical properties of tissue when the presence of a diseases is suspected. A typical use of this technique is in the breast cancer examination: the cancer is often revealed as a stiffening of glandular tissue, which would be normally soft. Even though palpation remains an important tool for clinicians, its limited use only to accessible tissue, its limited disease detectability and spatial discrimination, and the subjectiveness of its interpretation, motivates the need to improve the mechanical properties detection of

1. Acids are ionic compounds that release H+ when in contact with water. LABORATORY EXERCISE #3: Acids, Bases & pH

According to Erco Worldwide, “Hydrochloric acid, also known as muriatic acid, is an aqueous solution of hydrogen chloride gas”. By looking at the word, “hydrochloric”, people may believe that this chemical is only formulated by the elements hydrogen and chlorine but are also generated by other methods. Hydrochloric acid is also created through, “the chlorination of organic chemicals . . . the salt-sulfuric acid production process; and, as a co-product in the manufacture of silica” (Erco Worldwide). This chemical can be produced easily through the various methods presented, leading to the widely uses that this chemical has in the world. Erco Worldwide points out that, “The largest end uses for hydrochloric acid are steel pickling, oil well acidizing, food manufacturing, producing calcium chloride, and ore processing [to name a few]”. Humans also produce hydrochloric acid to digest food. Hydrochloric acid possesses its own set of dangers and needs a set of safety tips to protect themselves. Hydrochloric acid is a common chemical that has many uses, types of exposures, and its own set of safety procedures.

A neutralization reaction is a “reaction between an acid and a base” (Burdge 365). In this case, the acid is often an Arrhenius acid—a substance that ionizes in water to produce protons (H+), while the base is often an Arrhenius base—a substance that ionizes in water to produce hydroxide ions (OH-). A neutralization reaction between an acid and a base typically occurs in an aqueous environment in which all the reactants are dissolved in water. The products of a neutralization reaction are water, which is formed from the protons (H+) of the acid and the hydroxide ions (OH-) of the base, and a salt, which is “an ionic compound made up of the cation from the base and the anion from an acid” (Burdge 365). A simple example of a neutralization reaction is the reaction between aqueous hydrochloric acid (HCl) and aqueous sodium hydroxide (NaOH). Hydrochloric acid donates its protons (H+), and sodium hydroxide donates its hydroxide ions (OH-) to form liquid water. Then, the remaining chloride ions (Cl-) from hydrochloric acid combines with the sodium cations (Na+) to produce the aqueous

The MRI – Magnetic Resonance Imaging – is a non-invasive medical procedure that uses a powerful magnetic field and radio frequency pulses to produce detailed images of soft-tissue, organs, blood vessels, bone and nearly all other internal body structures. These detailed images allow physicians to evaluate various parts of the body and diagnose and treat various medical conditions. Unlike X-rays and CT scans, MRI machines produce 3D images of the body without the use of ionizing radiation. The traditional MRI machine is a large cylindrical tube surrounded by a powerful magnet, with the patient situated on an examination table that slides into the centre of the tube. Doctors often use the MRI to view

The idea is that the number of Hydrogen ions is changing as a result of the new equilibrium. This new equilibrium will either have less product, meaning increased pH; or more product, meaning decreased pH. The exception to this is Water and solutions with a pH of 7. This is because the amount of Hydrogen and

Bioinformatics is the applications of computers, software, and mathematical models to the management of biological information from large data sets. It is the storage and analysis of biological information by the use of computers. Computers are used to gather, store, analyze, and integrate information that can then be applied to gene-bases drug discovery and development. This has become an essential part of biological research activity, and is rapidly becoming as ordinary in biosciences as molecular biology has been since the 1980s. The science of Bioinformatics, which is the melding of molecular biology with computer science, is essential to the use of genomic information in understanding human diseases and in the identification of new molecular targets for drug discovery (What is bioinformatics). The primary goal of bioinformatics is to increase the understanding of biological processes. It is the "determination of the sequence of the entire human genome (approximately three billion base pairs)” (What is bioinformatics). This is done so differently from other approaches, however, due to its focus on developing and applying computationally intensive techniques to achieve this goal. "With bioinformatics, scientists can compare data from genetic material of a variety of living things, from tiny bacteria to large organisms, such as humans (Bioinformatics, 2012).
