PH indicator

Fluid regulation is very vital to homeostasis. If electrolyte levels rise or fall beyond normal limits, many bodily functions will eventually fail to progress at their normal degrees. Maintaining normal pH levels is also important for normal body functioning mainly because small alterations in pH can make up important changes in our metabolism. Electrolytes are minerals which mean that they carry ions and salts in our body that have an electric charge. They can be found in our urine, blood…

central location of the fish kill site, the salinity level should be between 0.5 to 35 ppt. The typical pH range for an estuarine system is between 5 and 9, which is the range most finfish populations adapt to live in (pH, 2012). The main chemical species responsible for affecting the pH include the levels of oxygen and carbon dioxide (pH, 2012).…

A different type of Japanese bamboo had been studied by Phong et al. (2012). Moso bamboo was harvested and processed using several methods to obtain the fiber. In alkali extraction method, the bamboo was cut into thin slabs with length and thickness of 25 cm and 3 mm, respectively. The slabs were immersed in different concentration NaOH solution (1%, 2%, 3%) at 70 ⁰C for 10 h. This study showed that only 1% NaOH resulted in higher mechanical properties. The roller looser was then used to produce…

just under 15,000 gallons of water. Once organisms swim into a mesocosm, they are sealed and the pH of the water is lowered to predicted pH level of 7.8 at the end of the century. A pH of 7.8 has been observed to slow some fish larvae growth and present abnormal behavior within species. Some abnormal behaviors from species including clown fish and sea snails were observed swimming toward predators. The pH of the solution is lowered by introducing carbon dioxide into the solution. Another great…

Effect That pH Has on It Abstract - The purpose of this experiment was to determine what variables affect the rate of photosynthesis. The variable tested was the pH level of the “environment” and this was tested using leaf discs from a plant. By testing the leaf discs in different pH levels of two, four, six, eight, and ten, it was found that the rate of photosynthesis was at its highest in a pH of six. It was also found that the rate of photosynthesis was at its second highest at a pH of…

Number: V00827823 The effect of different pH and temperature levels on the activity and action of catechol oxidase used from a solanum tuberosum specimen Abstract The various effects of temperature and pH on the enzyme activity and action of catechol oxidase, an enzyme containing copper which oxidizes phenols such as catechol with the use of dioxygen, were examined throughout several trial procedures. The experiment was conducted to determine the optimal pH for an enzyme to carry out its…

study 1 The acid base balance of the body is mainly regulated by respiratory and renal system together with the body ‘buffer system. For the body to function normally, the hydrogen ion (H+) needs to be concentrated within a narrow range, represented as pH, which determines the acidity and alkalinity of a solution. Changes in the bicarbonate (HCO3) concentration causes metabolic acidosis or metabolic alkalosis while changes in the rate of alveolar ventilation and carbon dioxide concentration…

Kalyani et al (2009) studied an isolated strain of Pseudomonas sp. SUK1 from the waste disposal sites of local textile industries in India, with the objective of evaluate an ecofriendly textile dyes biodegradation. To isolate the microorganism, they first collected a soil sample from the waste disposal site and inoculated the sample in a nutrient medium with a dye. Then they incubated and plated in agar with dye. The colonies that had a halo of decolorization were selected to be submitted to…

strong-weak titrations allow for an in depth analysis of the half-equivalence point as well as buffers. The half equivalence point allows the calculation of pH from pKa, as they are both equal at the half equivalence point, proven by the Henderson Hasslbach equation. It was Henderson in 1908 that created an equation allowing for the logarithmic calculation for pH from a buffer and the pKa which consequently lead to the knowledge and applications of buffers that we have today. Buffers were also…

DUA. Key soil characterisation of these four soils is summarised in Table 4.2. The reason why these four types of soils were chosen for this chapter was that they had distinct soil parameters in terms of total organic carbon (TOC), Fe oxide, Al oxide, pH which have been observed as important controllers for bioaccessibility of As, Cd and Pb reported in previous chapters. MGA soils contained a high amount of TOC (8.37 %), Fe oxide (12.49 g kg-1), Al oxide (12.6 g kg-1) whilst few TOC (1.48 %), Fe…
