Strong acid

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…

is controlled by the hypothalamus and pituitary gland by a buffering system. A buffer solution is used to maintain the pH at a safe acidity. “A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid” (Boundless, 2010) Equation 1 – Generic Buffer Equation HA (aq) + H2O (l) --> H3O+(aq) + A-(aq) Note that equation 1 is reversible, and all equations that are reversible have to be at a state of.equilibrium.…

This chemical reaction involves neutralization, where an acid and base react to produce a neutral solution of salt and water. As this information is provided, the known concentration of NaOH(aq) is 0.25M. It is necessary to rinse out the burette with sodium hydroxide solution before starting titration, as the concentration of the base can be affected by the water used to clean the burette. At the same time, when cleaning the burette it may not have been washed thoroughly . By rinsing with…

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…

By using the bioinformatics information, we can determine that the non polar amino acids affect the bonding with hydrogen bonds. This means that the pH of the enzyme will be physiological. It can work better at a pH concentration of 7, and actually the cells can survive in that environment. Meaning, enzymes can work well with this concentration of pH, so it bonds do not break easily when it can be saturated of acid or base. 4. As our experiment says, the three different amylase will have…

breaking down water molecules is called photolysis. In the dark reactions, glucose is made. Carbon dioxide and ribulose bisphosphate, which is also called RuBP, unite to form rubisco, which then splits to make two phosphoglyceric acid molecules, the phosphoglyceric acid is sometimes called PGA. PGA gets converted to phosphoglyceraldehyde or PGAL. Many PGAL is used to make more RuBP. This is called the Calvin Cycle. Photosynthesis is affected by many factors, like the amount of carbon dioxide in…

to be for the fact that both Methanol and water have strong properties of hydrogen bonding. While we thought water wouldn't mix , we predicted Dichloromethane , n-Pentanol,Methanol,Toulene and Water to mix. Again our predictions were not exact in that water did not mix with any of the substances except Methanol. This again was due to water's strong properties of hydrogen bonding, resisting to interact with molecules that do not also have strong properties of hydrogen bonding. While n-Pentanol…

moiety was also protected as its O-Boc enol carbonate (Figure X.X.X). Transient in situ O-silylation facilitated the preparation of bis-N-Boc nucleosides from unprotected sugars. This strategy allows the protection of nucleosides with a base-stable and acid-labile group suitable for the preparation of base-sensitive oligonucleotides as well as for further manipulation. However, the utility of this diBoc carbamate protection is yet to be explored in oligonucleotide…

measure the enthalpy change of acid-based chemical reactions; part 1 reacted NaOH with HCl and part 2 reacted KOH and HCl. In parts 2, 3, and 5, 2.0 M of KOH, HCl, and NaOH were each separately diluted with water, respectively. After collecting the data, the goal of the lab was to then calculate the enthalpy change by using linear regression models on Excel and the appropriate equations relating to enthalpy…

and [HI] will decrease. 4. 20 grams of magnesium were placed in a conical flask. Which one of the following solutions, if added, would produce 100 mL of hydrogen gas the fastest? A. 100 mL of 4 M sulfuric acid B. 200 mL of 2 M sulfuric acid C. 400 mL of 1 M sulfuric acid D. 50 mL of 8 M sulfuric acid 5. Why does the rate of reaction increase when powdered calcium carbonate is used instead of marble chips? A. The powdered calcium carbonate acts as a catalyst. B. There is an increase of the…
