Acid dissociation constant

of determining an unknown acid or base, anion and cation test were performed. These tests allowed for the components of the solutions to be identified, therefore, achieve the second goal. The pH was also used in to help find the identity of the unknown solutions and it was used to draw conclusions about the solutions. Dilutions were used to help understand the different behaviors of different concentrations. Household items were used to help apply basic theories about acids and bases such as pH.…

Title: To what extent does strong and weak acids differ in affecting the course of titrations. Introduction: The real life application that comes from this experiment links to agriculture. In the past decade, industrial dumping has become a controversial topic. Dumping hazardous wastes into river, ocean, and soil has resulted in a dramatic change in pH of the non-renewable resources and leads to a destruction in the ecosystem. Specially in agriculture, crops cannot grow in acidic soil, so it is…

equilibrium of the molecules. During this lab we will separate two compounds from one solute that will be formed by amalgamating a ‘slurry’ – provided by the instructor. Resin or cellulose is used to create a sound support unit in order maintain a constant positive or negative charge respectively, this will allow separation to occur when equilibrium is shifted during the reaction. The column will have a support unit – composed of either cellulose or resin, inserted with varying concentrations of…

respiratory acidosis and respiratory alkalosis, and metabolic acidosis and metabolic alkalosis. The purpose of this paper is to provide you with the definitions, causes, symptoms, and treatments of these conditions. Acidosis is an excessive amount of acid in the blood that causes pH levels to fall below 7.35. Alkalosis is an excess of base in blood that causes pH to rise above mpl7.45. With that being said, in my first section, I will be talking about respiratory acidosis. In the second…

To determine optimal pH value for the hydrolysis of p-NPG by leukocyte GCase, we examined effects of variable pH (4.0-5.5) at a constant substrate concentration (5mM). Figure 1 shows the pH activity curves of leukocyte GCase assayed in the presence and absence of 6 mg per ml Sodium taurocholate. In the absence of the pure sodium taurocholate, the activity in the range of pH 4.0-4.8 was considerably lower. However, in the presence of pure Sodium taurocholate, leukocyte GCase was optimally active…

This experiment exemplifies the effects of the concentration of hydrogen on the strength of bone. As bone is majorly composed of calcium, and knowing that acids want to neutralize. Throughout the experiment, results show that the strength of the bone was compromised in acidic situations, but rather unaffected in situations where the concentration of hydrogen was basic. Even more noticeable than the change in pure tensile strength is the change in the maximum deflection before fracture.…

analyze how the addition of acid or base and dilution affected the measured pH. The results showed that when the buffer systems were under acidic conditions their pH values decreased and increased when exposed to a basic environment. The main goal of the ionization of the amino acid experiment was to titrate an unknown amino acid with a strong base in order to produce a titration curve. The titration curve was used to evaluate the molecular weight of unknown amino acid #1 and proved that its…

The values that arise from the feed analysis were: the dry matter, crude protein, acid detergent fibre, neutral detergent fibre, pH level and ash. Specifically, the value for the dry matter is the corrected value in order to allow for acids, volatile acids and other components that lost on oven drying. The crude protein which is determined from the total nitrogen of silage is 88.33 (g/kg DM). The value of the acid detergent fibre which is a measurement of lingin, cellulose and lignified nitrogen…

the “normal” range for the human body? If not, when was the pH value outside of the normal range, and what acid/base imbalance did this pH value indicate? No, acidosis occurred at 40 seconds when the pH dropped out of “normal” range to 7.29. 6. Did the PCO2 level change during the course of this run? If so, how? Yes, the Pco2 level elevated. 7. If you observed an acid/base imbalance during this run, how would you expect the renal system to compensate for this condition?…

Experiment #9- Acid Base Titrations II: Potentiometric and Indicator Titrations Introduction- In this experiment, the reactions of three different acids with a strong base are studied by observing how the pH of the solution changes as the titrant is added. A plot of pH versus amount of titrant added will be constructed. Such a curve is called a pH titration curve. The equivalence point of the reaction will be determined from an analysis of the pH titration curve, and by the use of acid-base…
