Weak acid

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…

Acids and Bases are solutions, and can be found everywhere in the world. They can be found in food, drinks, around the house, and in the environment around you. Acids and Bases are used by people, animals, and even plants for many different purposes (Buthelezi et al. 634). A solution is a homogenous mixture, which is a mixture with a composition that is consistent throughout the substance (Buthelezi et al. 634). Solutions are comprised of the solute and a solvent. The solvent is the most…

in USA and is mainly produced by the Solvay process: NaCl + NH3 + CO2 + H2O NaHCO3 + NH4Cl Sodium bicarbonate, when exposed to an acid, releases carbon dioxide and water: NaHCO3 + HCl NaCl + H2O + CO2 (gas) Above 70°C, it gradually decomposes into sodium carbonate, water and carbon dioxide: 2 NaHCO3 Na2CO3 + H2O + CO2 It is used as an antacid to treat acid indigestion and heartburn. Sodium bicarbonate is also used to absorb moisture and odours; an open box can…

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…

experiment was to measure how much the pH changes when an individual adds a certain amount of acid or base to water, biological buffers, and other biological solutions. It is vital to study the changes in pH because a slight change in pH in an organism’s body can disrupt metabolism activities and even cause death. To accomplish the purpose of the experiment, an individual will add certain amounts of acid or base to water, biological buffers, or other biological solutions. pH is a measure to…

combined with an organic mixture of CHCl3/MeOH, to isolate the lipid layer. By centrifuging the organic solvent with milk the heavy lipids sink to the bottom while the water layer which contain water soluble carbohydrates, peptides and small amino acids float to the top. Since the organic solvent had low boiling points the lipids from the organic layer were easily obtained by evaporation. Methods Refer to page 1.2-1.3 in the BCEM 341 Manual Lab 1: Lipids. [1] Results Refer to the attached…

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…

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…

This is because in a strong acid/ strong base neutralization, the strong acid and strong base dissociate completely into ions. Therefore, all mole added to the solution would essential react and produce heat. Where as a weak acid would only partially dissociate into ions while the strong base would dissociate into complete ions. Since the weak acid produces less ions to participate in the neutralization, less heat would be produced because…

go to 7 or 7.8, it can be deadly. The blood buffer contains carbonic acid which dissociates into bicarbonate acid and hydrogen ions. This equation can also be reversed; it is a chemical equilibrium. If the hydrogen ions rise, bicarbonate accepts the hydrogen ions and the equilibrium shifts left thus making the blood acidic. When the blood becomes acidic, acidosis…
