Soil pH

Normal pH within the blood can range between 7.35 and 7.45 arterial and venous is 7.32 thru 7.42. Normal HCO3 for arterial is 22 thru 26 mEq/liter and venous is 19 to 25 mEq/liter with PCO2 normal for arterial 35 thru 45 mm Hg and venous 38 thru 52 mm Hg. Normal PO2 is 80 to 100mm Hg for arterial and venous is 28 thru 48 mm Hg. Acidosis can affect the central nervous system within the body and left untreated can lead to death. Alkalosis affects the central nervous system which can cause muscle…

Most aquarists that have an irregular pH would rather use a natural means of balancing the pH of salt water because of the beneficial effects on, not only the overall water chemistry, but the non-lethal effects on the waters inhabitants. A very common pH balancer is crushed coral, which is a chemical mixture of solid aragonite. Aragonite is a polymorph of calcium carbonate, and a natural pH buffer. Crushed coral could quite possibly be the solution for reversing…

productivity, such as pH and substrate concentration. Every enzyme has a different “optimum pH value” (Factors Affecting Enzyme Activity). If the pH that the enzyme is working in is at this optimum pH value, it will work at its optimum speed. If not,…

The experiment performed provided insight on the importance of acid-base interactions and the pH of solutions that are involved in a variety of aspects including industrial, environmental, and biological contexts. Back titration was used to determine the number of moles of HCl acid that were neutralized by a single tablet of several variations of commercial antacids. In theory, the antacid that neutralized the largest number of moles of acid was found to be the most effective. The results…

are typically measured as the amount of products produced per unit of time for a single given concentration3. Enzyme kinetics can be affected by the concentration of the substrate, the presence of inhibitors, as well as changes in temperature, and in pH. A substrate is known as the substance that is catalyzed by an enzyme2. An increase in substrate concentration leads to an increase in product formation due to a greater amount…

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 know what they are. “The word acid comes from…

affected by pH; the carboxyl groups have poor reactivity to EDC/NHS at pH <4.5, and NHS-esters are more susceptible to hydrolysis at alkaline pH values [18,19,20,41]. The amidation reaction of NHS-ester with amino groups is known to be most efficient at the pH values between 6 and 8; amino groups exhibit poor nucleophilicity to NHS-ester at low pH because of the formation of protonated amino groups, but amino groups have strong nucleophilicity, whereas NHS esters are unstable at high pH…

multiple trials with the macromolecules and test the pH levels throughout the course of the experiment. Materials and Methods The experimental design for our project was to simulate the digestion of carbohydrates, lipids, and proteins. We had set up trials for the pancreatic enzymes to break down these macromolecules and tested if macromolecule digestion had actually occurred, we also recorded the rate of their digestion by measuring pH levels. In trial 1 of our experiment we had simulated…

body’s pH balance in check is always important this because proper body function can happen and we remain healthy. If your blood pH were to drop below 7.35 you would develop a condition called acidosis. Then depending on the cause of this acidosis whether it be the kidneys or the lungs would determine the kind of acidosis. If it is the kidneys causing the acidosis we would call it a metabolic acidosis, where is if it were the lungs it would be called a respiratory acidosis. Know if your blood pH…

Introduction A hydrogel is a jelly-like material made of a network of polymer chains capable of absorbing a significant amount of water; enough to make water constitute 40 to 90% of the material’s weight. Hydrogels have numerous applications but among their most noteworthy are those related to the medical field.1 Numerous hydrogels exhibit a high degree of biocompatibility, making them particularly suitable for controlled and sustained release drug formulations.1,2 The wide variety of hydrogels…
