Acid dissociation constant

cause of acidity in water. Photosynthesis, respiration and decomposition all contribute to pH fluctuations due to their influences on CO2 levels. While carbon dioxide exists in water in a dissolved state, it can also react with water to form carbonic acid H2C0. It is mostly inferred that the area is surrounded by lots of eco systemic processes with lots of plant…

1) The samples that would float on water are water (if in an ice form), oil, methanol, 2- propanol and lead because these materials are less dense than water, which leads to them laying on top, or until they dissolve. The samples that would sink in water include aluminum and copper because they are denser than water. 2) The order of the four liquids that I would layer them in a graduated cylinder from bottom to top consist of: water, oil, 2- propanol, and methanol. 3) Working with specific…

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…

Comparing the masses, after and before reaction Aim To determine if mass is preserved in a chemical reaction conducted with vinegar and Sodium bicarbonate. Hypothesis: The mass of the flask and vinegar after the reaction will be less due to the fact that it is losing the gas which is being produced when the elements are mixed. However part B will be altered as the gas will be preserved inside the balloon. Apparatus  Balance  Sodium bicarbonate  Spatula  Measuring cylinder  2 conical…

1. Do supplements that contain a higher protein content have a lower sugar content? 2. Biuret’s Reagent is a chemical indicator that detects protein and turns violet with the occurrence of peptide bonds. Lugol’s reagent is a chemical indicator that detects starch and turns into a black brown color as a result of the formation of polyiodide chains. Benedict’s reagent is a chemical indictor that detects monosaccharides and sugars and the observed change for a positive reaction is precipitation.…

Almost all of us have to deal with cough and cold, especially during winter time, which can be really annoying, but beside that, if you don’t treat them properly and on time, they can turn into an extremely irritating and dangerous disease. Dry cough is really annyoing and uncomfortable which makes you feel worse than you should. In most common cases, the people with cold and cough are always seeking for pills and syrups in the pharmacies. Probably, they don’t know that there is easy and…

There are several physical and chemical methods, of which the simplest method involves the reduction of the metal salt AgNO3 by NaBH4 in water. Wiley and his coworkers synthesized three different shapes of silver nanoparticles using chemical method, in which ethylene glycol used as both solvent and reducing agent [5]. This group synthesized cubic silver nanoparticles by reduction of silver nitrate (AgNO3) with ethylene glycol in the presence of Polyvinylpyrrolidone (PVP) and HCl. After synthesis…

1. Fit the stem of a funnel inside the short end of a straw. Push the funnel in as far as it will go. Securely tape the straw to the funnel. Repeat for the second straw and funnel. 2.Push a straw-funnel assembly through the hole near the bottom of each container so that the funnels are on the inside of the containers. Adjust the straw-funnel assemblies so that the funnels face up. Put some modeling clay around the hole, on the outside of the container, to hold the funnel in place. 3. Start by…

More conjugated compounds absorb higher wavelengths/lower energies because as the wavelength increases the HOMO/LUMO gap (ΔE) decreases which is due to the compression of multiple molecular orbitals (ψ). According to Klein, the Ketchup stain (lycopene) on a shirt and upon application of bleach (NaClO), it breaks lycopene’s conjugation, therefore causing a decrease in conjugation; which directly correlates to the stain no longer being visible to the eye but when illuminating the shirt with…

and CO2, there is a compromise of lactate acid and acid- base balance from a high intensity exercise. The factors that avoid this change in the homeostatic limits are PO2 and PCO2, and pH. Which are maintained form increase in oxygen delivery to the alveoli and CO2 exhalation from the body (King, 2018). Acid- Base balance are affected by hydrogen ions which are formed from the lost of electrons. When a molecule releases hydrogen ion it is determined as acid, and when it is bind with hydrogen ion…
