Acid-base homeostasis

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…

Systems As humans, we constantly need to regulate our bodily pH. This regulation process is called homeostasis, and 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) +…

Bases are electrolytes that mix with hydrogen ions. Hydrogen ions are in the body because of respiration. They can also be made because of oxidation of fatty acids, amino acids that contain sulphur and nucleic acids. The amount of hydrogen ions that in the body can be regulated in many different ways: Acid base buffer systems are located in body fluids and are chemicals such as the buffer phosphate system…

Acid base balance is a part of homeostasis for maintaining the pH of the body. It is necessary for the functioning of enzymes and structural integrity of proteins. In case of an unacceptably large variation in the pH of the body, the enzymes lose their normal function, the proteins get denatured, and in extreme cases, death might result. The normal pH of human blood is 7.4, the acceptable range being 7.35-7.45. In the…

on it which would have been removed with the stick. It is less clear why the benzoic acid was overproduced. Some of the organic layer may have been drawn off with it, but the vacuum filtration should have left only the benzoic acid. There could have been an error in weighing the filter paper before the procedure. There also could have been contaminants in the basic extract, causing more than just the benzoic acid to be filtrated. There is also the chance that too much starting material was…

Fig 4.12 shows the comparison of product density of hydrotreated GO obtained using CAT-E and CAT-C. The density of hydrotreated GO from CAT-C at 370◦C was 0.8148g/ml whereas at the same temperature the density of hydrotreated GO obtained from CAT-E was 0.8302 g/ml despite sulphur and nitrogen in the GO has been reduced to less than 50 ppm and 1 ppm respectively. The reason for higher density would be due to higher aromatic content in the hydrotreated product obtained from CAT-E. This indicates…

One of the parameters that determines water quality is pH. It is defined as the negative logarithm of the hydrogen ion and is intended to be a measurement of the balance of acids and bases. Temperature affects pH. In pure water, a decrease in pH of 0.45 occurs when temperature is increased by 25°C [11]. There are several methods for measuring pH. The most common is the use of a glass electrode sensible to it, a reference electrode and a measurement device. Another method is the use of…

A clean flame test wire was inserted into 0.2 M NaCl and also placed on the flame reputedly. A bright yellow persistent flame was a positive test of sodium being presented, then repeat the same instructions for the unknown ion. After the flame test wire was clean 0.2M KCl was dipped into the flame resulted a lavender color after several trials as well as the unknown solution. 10 drops of 0.1M Ca(NO3)2 in a test tube and 2-3 drops of 1M Na2C2O4, a white precipitate of calcium was present. The…

Purpose: To find the pH of different household items and to see what substances are acids or bases. To see how different substances neutralize each other. Hypothesis: I hypothesize that cleaning products will be bases and foods and substances we ingest will be acids. Materials: • Oil • Finesse Shampoo • Anti Freeze • Drain Opener • Hand Soap • Vinegar • Oxy clean • Pine-Sol • Hydrogen Peroxide • Apple Juice • Ammonia Procedure: 1. All materials were gathered, and safety goggles were put on.…

a pH of seven, however most water, either from the tap or rain water, are not neutral (they do not have a pH of seven) instead it varies slightly and normally ranges from about 4.0 to 5.5 on the pH scale, which shows that they are slightly acidic. Acid rain is due to the chemical reaction that takes place…
