When pH is high which means more OH⁻, then aluminum ions will react with hydroxide ions to form aluminum hydroxide. Phosphate ions are acting as a natural buffer. If the equipment is not washed with acid, it would cause an error. This is because the phosphorus analyzing is dealing with low concentration of phosphorus and it is easily contaminated by detergent and other chemicals and it has to be washed by using an acid and also it has to be rinsed with distilled water once it is rinsed with acid. Also refer to section 4 (discussion).
The three things that can cause the enzyme to denature is a large change in pH level, High Temperature, and substrate concentration. According to our knowledge, we know that a large change in pH will cause instability in the protein structure thus resulting in denaturation of the enzyme. From the data, we can see that pH 3 (total:6.3) and 10 (total:6.2) were the slowest because pH 3 is probably the highest acid and pH 10 is the highest base. The highest acid or base pH represents a large change which would cause the enzyme to denature. The fastest pH was 6 (total:34.5), and it seems that there wasn’t a large change which resulted in a stable structure.
The resulting molten material is called the blister and contains about 99% copper by mass. (Cavette, 2007) Refining The copper blister is 99% copper but it still have a higher level of sulfure, oxygen some other impurities and by the reason it has to be further refined in order to purifies the cupper, this done by fist firing refined before it is sent to the final electro fining process • The blister copper is heated in in the refining furnace that is similar to the converter ,air is blown into the molten blister to oxides the impurities and a sodium carbonate is added to remove traces of arsenic and the antimony, • The blister copper is heated in a refining furnace, which is similar to a converter described above. Air is blown into the molten blister to oxidize some impurities. A sodium carbonate flux may be added to remove traces • Then the purified copper in then poured into the molds to form large electric
The research had found that the greater intake of sodium which is the chemical present in salt will lead to the greater uric acid and albumin levels - are the greatest damage to thye blood vessels of our body. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3649719/ Type of
First prepare the buffer. The stock buffer should be kept in the refrigerator, but if not Possible, can be stored at room temperature for several weeks. Make working buffer Which can be stored at room temperature for a few days. Buffer should be pH 7.0 to 7.2. Although this is a higher pH than normally used to stain blood cells, the Parasites will stain darker and be more visible under the microscope.
More Maintenance Another disadvantage of using a salt water system is the fact that the hot tub will require more maintenance, which again can lead to more expenses. Usually, the salty water is corrosive, so all the metal parts may easily corrode, thus needing replacement at some point. High Water Temperatures In order to function properly, a salt system needs higher temperatures, 65° or higher, because otherwise it will produce little chlorine or even worse, it will automatically shut down. Therefore, you have to make sure that you keep the required temperature in order to make sure that the system works and there aren 't any
To determine the rate of reaction there are many method to be used for example, measuring the mass after the product has been added and measuring the difference in mass on the duration of a digital scale. Another method, which will be used in this experiment is using a gas syringe to measure the volume of the gas which has been produced. The cylinder inside, will be pushed out to show a quantitative presentation of the volume produced by the reaction. Hypothesis I predict that the more baking powder added to the vinegar, the more reaction will take place causing for more gas to be produced per 10 seconds. There will be a gradual decrease in difference between volume in gas per 10 seconds over the duration of time.
This results in swelling of the cell until the critical volume is reached, afterward the membrane at first leaks and then bursts releasing hemoglobin (Faulkner and king 1970 ). The osmotic fragility test can be performed on freshly taken red cells. The susceptibility to osmotic lysis is primarily determined by the surface area to volume ratio of erythrocytes .Increased osmotic fragility typically occurs in hereditary spherocytosis. Because of their reduced surface membrane area in respect to the cell volume, spherocytes take up less water in a hypotonic solution before rupturing than do normal blood cells. They cannot expand as much as normal discoid erythrocytes and are osmotically more fragile ( Roper and Layton, 2012
The long exposure to the low heat evaporated the water, thus increasing the concentration of Sodium Thiosulfate. The accuracy of the results was changed with the altered concentration. To increase the accuracy of the results, the blue flame should have been used to make the solution reach the temperature needed quicker. This would allow the Sodium Thiosulfate and the Hydrochloric acid to mix in a longer duration of
Thus, the amount of the carbon dioxide collected in measuring cylinder will be affected, causing the rate of reaction to be altered. In addition, the source of the random errors in this experiment is the widely spaced graduation mark on the 100mL measuring cylinder, result in variation in the eye level to determine the amount of carbon dioxide released and the amount of diluted hydrochloric acid used which may lead to the rate of reaction changes irregularly as the time taken to collect 30cm³ of carbon dioxide is affected. Equally important, the air movement in the room will also affect the rate of reaction as the air movement will affect the temperature, thus indirectly affect the rate of reaction. When magnesium carbonate reacts with hydrochloric acid, this is an exothermic reaction where heat will be release out and increases the rate of reaction. However, air movement in the room causes the advection of heat.
