Strong acid Essays

1. In step 1 HCl, a strong acid, was added one drop at a time to DI water. The addition of HCl to the DI water resulted in the pH going down. The first drop of HCl that was added caused the pH to go from 5.24 down to 4.20. The second drop caused the pH to go to 3.92, followed by the third drop which caused the pH to go to 3.79. The overall addition of HCl caused a 1.45 drop in pH. 2. Step 2 was the same as step 1 but NaCl, a salt of a strong acid-strong base, was used in replace of DI water. The

Monsieur Lantin and his lady had the perfect marriage, falling deeper in love with one another by each passing day. The rising theme of irony, however, proves that appearance can overshadow reality. It creates tension between an intended meaning and a literal statement, used as a form of dry humour to provoke the reader. Throughout his short story, The False Gems, Guy de Maupassant emphasizes several forms of irony to display the universal theme of deviousness. Monsieur Lantin’s lady was thought

twist up so in a startling way. To that investigate the proper reaction is straightforward, the young fellows had one vital complexity that drastically affected their destinies. Wes Moore made The Other Wes Moore to exhibit that if kids don 't have strong parental figures they won 't be powerful in life. There are a couple of conditions in which "other" Wes ' mother, Mary, does not give the heading that her youngster so wildly needs. In the wake of playing hooky and celebrating with his associates

The world is controlled by the economy. It’s a deathly cycle that never ends. People wake up every day and go to work or to school, anything that leads them to earning money. Money controls the world. Without money we are nothing, for we cannot survive if we cannot buy food or water. Some people, however, want to be wealthy in order to impress other people. For example, the mother in the story, The Rocking-Horse Winner already has a great amount of money, but wishes to be more wealthy. The story

Section 2: Analysis of Competition To discover effectual sources of competitive benefit, an analysis of the business’s structure should be taken on. Thus, to analyze the Tesco’s competitive atmosphere, Porter’s five forces of competition theory have been used as follow: threat of new entrants, power of buyers, power of suppliers, threat of substitutes and competitive rivalry. Threat of New Entrants Basically, the greater the barriers to entry are, the greater the possible

Fiver is a puny rabbit who has the intuition to predict when bad things are going to happen. Early in the book, he predicts that there will be an end to the warren that he lives, so Hazel, his more confident brother, gathers and leaves camp with about a dozen other rabbits. They go through several adventures, encountering predators, and a farm where they narrowly escape. Soon, they find a very habitable field at the top of the hill called Watership Down and they set up a warren there. Two lucky

FHIL, better known as Florida Hospital Innovation Lab is a center based on the ideals of human centered design through the creation of an innovation. On Tuesday March 28th, I visited FHIL for the first time and went through the design making process with the five steps consisting of: empathy, reframing, ideate, prototyping, and testing. The experience began as people were split into teams of five people, each with a different challenge they’re trying to solve. My group’s challenge was to develop

on Your Face and See the Results If you are insecure due to eczema on your face, use apple cider vinegar to treat it as well as other uncomfortable skin conditions. Why is apple cider vinegar effective against eczema? • Malic, lactic and acetic acids in apple cider vinegar contain anti-fungal and antibacterial properties which make this vinegar effective against itchiness, skin infections, inflammations and dry skin. • The renewals of the cells will also be increased due to the beta-carotene in

Discussion: End point in this acid-base titration experiment refers to the point where the chemical reaction has reached its conclusion and no additional titrant should be added. The end point of this experiment can be obtained when the indicator used changes colour. For example colourless to light pink when phenolphthalein is used and red to orange and subsequently yellow when methyl orange is used. Equivalence point, also known as stoichiometric point in an acid-base titration refers to the point

titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌ H2CO3 The popping sound we hear when we open the can of fizzy drink, the bubbles and sparkle we see in the soft drink, and the feeling of bubble popping on your tongue, all of these are due

Point out how excess acid contributes to the discomfort known as indigestion. Explain how the stomach secretes a mucous layer, which protects it from being damaged by the hydrochloric acid it produces. Abstract Hydrochloric acid, which is also called HCl, is a highly corrosive acid. It is a strong mineral

Bradley Trotter & John Fussell Chem 1121-42 March 29th, 2018 Identity of an Unknown Weak Acid Lab Report Introduction: Being able to determing the molar mass of an unknown solution is one of the many ways to identify what the unknown solution is. The use of titrations and LoggerPro, make extrapolating data more precise and will produce more accurate results than if done manually. By comparing the caculated molar mass, and pKa values, with accepted values a hypothesis can be made to the identity

(Environment Canada 2012). Through a dual oxidation process, Nitrate is formed in a reaction of Nitrogen with Ammonium ion producing fertilizer and manure. The oxidation state of a nitrate compound is 1- . Nitrate is the conjugate base of nitric acid (HNO3), a strong

The temperature of the water was then recorded to the nearest 0.1⁰C. Then the melting points of phenylacetic acid, o-anisic acid, and benzilic acid were determined by the use of a Mel-Temp. The unknown sample was obtained from the chemical stockroom. A small scale of crystals from unknown was placed in a test tube with the following solvents: cyclohexane, hexane, toluene, diethyl

Concept 3.1: Nucleic Acids are Informational Macromolecules Nucleic acids are polymers and there are two types, Dna and Rna. Dna is where the information is stored and determines how functions in the body is carried out and Rna how mediates the information. The monomers of nucleic acids(polymers) are made up of nucleotides. Nucleotides are made up of three parts:nitrogen containing base, a pentose sugar and anywhere from 1 to 3 phosphate groups. Nucleosides are molecules that have a pentose and

which was composed of 50% fluorene, 42% o-toluic acid, and 10% 1, 4-dibrombenzene. Techniques of extraction and crystallization was used to perform the procedure. The two major compounds in the mixture (fluorene and o-toluic acid) was collected; these were separated by two major methods. The o-toluic acid was extracted first by using macroscale extraction and testing for acidity. By adding a strong acid to the aqueous layer, which contained o-toluic acid, the solution becomes acidic and also allows the

Sodium carbonate (molecular formula: Na2CO3), is the water soluble sodium salt of carbonate. The pure product appears as a while, odorless powder with a strong alkaline taste. It has high hygroscopicity. It can be easily dissolved in water to form an aqueous solution with moderate alkalinity Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate) is chemical compound with the formula NaHCO3. It is a salt composed of sodium ions and bicarbonate ions. Sodium bicarbonate is a white solid that is

Acid and base balance of body is normally strongly controlled, keeping the arterial blood pH between 7.38 and 7.42. Acid and base is also important in human homeostasis regarding the appropriate balance between acids and bases; this is also called pH. The body is very sensitive to its pH level, so strong mechanisms exist to maintain it. When pH is imbalanced the protein become denatured and digested, enzymes lose their ability to function, and can cause death. Metabolic Acidosis and Alkalosis: Metabolic
