This research project will use mixed research methods in order to obtain qualitative and quantitative data. The qualitative data will be acquired through the review of literature as well as the analysis of other sources so that one can understand what previous research was done on the topic and how to formulate a response to the hypothesis from one’s own discoveries as well as other research sources. The primary research is found through quantitative data, which will be attained from an experiment that will determine whether the hypothesis is correct or incorrect. This research project will be done in order to prove which chemicals and substances will increase the pH of the blood by initiating certain processes in the body which will cause …show more content…

There was a strong odor similar to the smell of vinegar given off. After the solution was heated and the solid dissolved, 0.2 mL of hydrobromic acid was added to the test tube. The solution turned a bright yellow color after the hydrobromic acid was added. The solution was heated in a hot water bath for 5-10 minutes and then let cool. After heating, the
Pour a sufficient amount of room-temperature water (about 16 oz) into a large glass. 2. Add a tablespoon of salt to the water and stir well. 3. Drop an Alka-Seltzer tablet in an empty water bottle.
Goals The primary goal of this experiment was to identify an unknown compound by running various tests to determine the qualitative solubility, conductivity, and pH value of the compound. Tests were also performed for the presence of specific cations and anions in the compound. The second goal was to discover the reactivity of the unknown compound by reacting it with different types of substances. The third goal of this project was to calculate the quantitative solubility of the unknown compound in water.
To do the temperature and dissolved oxygen tests, stick the probe in the water, and it will show numbers. One will be the dissolved oxygen in ppm (parts per million) and the other will be the temperature of the water. To do the pH test, stick the pH paper in the water and compare the color it turns to the scale. To test nitrates, put clear water in a container and dirty water in another, and put powder in them. Shake them and then compare the color they turn to the scale.

According to the research done in the Literature Review, acidosis is usually caused by a buildup of lactic acid in the body due to muscle exertion.
Enzymes are a form of protein that lowers activation energy and speeds up reactions as a catalyst. They are made by the stringing together of an abundant amount of amino acids and folded into a specific shape for chemical reactions. Turnip Peroxidase is the enzyme used in this lab and is derived from the vegetable. Enzymes are not used up or permanently altered by their environment Peroxidases are found in a range of organisms and function to break down alcohol (H2O2) and creates byproducts of oxygen and water. In this experiment, the reducing agent guaiacol is added with the substrate, hydrogen peroxide, to create water and oxygen.
Materials: The materials that I will be utilizing during these experimentations are three to four ice cubes, one cup for measuring, six unblemished cups, one stopwatch, one hot water source, three tablets of Alka-Seltzer, one thermometer that measures from negative
Weighed 1 gram of NaC2H3O2 and mixed it with ionized water. Boiled 12 mL of 1.0M Acetic Acid added into a beaker containing the sodium carbonate on a hot plate until all the liquid is evaporated
The soda water will be stored in 5 different temperatures : 5℃, 15℃, 25℃, 35℃, and 45. The desired temperatures will be achieved by using the water bath and refrigerator. I chose phenolphthalein as the indicator, because it is commonly used for titration and is a weak acid. Phenolphthalein is usually used when the solution is strong base and weak acid. When it is added into an acidic solution, the solution will be colourless; when it is added into an alkaline solution, the solution will turn pink.
Materials and Methods The chemicals used to perform this experiment were distilled water, sodium chloride (NaCl), ice,
Paragraph 1 The objective of the experiment is to test; how will water temperature affect the rate of reaction of an alka-seltzer tablet? The dependent variable of the experiment is the dissolving time. When an alka-seltzer tablet starts to fizz it begins to dissolve, due to the citric acid and sodium bicarbonate the tablet contains (Clark, “Why does Alka-Seltzer fizz?).
11) After you have prepared the dilutions, clean the outsides of the cuvettes with a paper towel. 12) Place the blank tube (tube 0) in the spectrophotometer. Since distilled water has no color it will not absorb any light so the absorbance number would be zero and this done to test the absorbance scale on the Spectrophotometer for the purpose of having it calibrated correctly. 13) Set the spectrometer to a wavelength of 530 nanometers. 14) Place the cuvettes (numbers 1-6) with the appropriate substance and record it’s reading in the data table.
In this experiment three gummy bears were put in different solutions to observe the effect of osmosis on them. The independent variable in this situation are the following types of water: tap, salt, and sugar. The dependent variable is the change in mass and volume from all three gummy bears. The gummy bear brand, the environment, and the amount of time in the solution are the constants of the experiment. After the experiment is competed, one can determine how the osmosis changes the gummy bears.
Introduction Buffer is a solution that resists a change in pH when bases or acid are added. Solutions that are acidic contain high concentrations of hydrogen ions (H+) and have pH values less than seven. Buffer usually consist of a weak acid, and its conjugate base or a weak base and its conjugate acid. The function of buffer is to resist the changes in hydrogen ion concentration as a result of internal and environmental factor. This buffer experiment is important so that we relies the important of buffer in our life.
The chemical equation for this experiment is hydrochloric acid + sodium thiosulphate + deionised water (ranging from 25ml to 0ml in 5ml intervals) sodium chloride + deionised water (ranging from 25ml to 0ml in 5ml intervals) + sulphur dioxide + sulphur. As a scientific equation, this would be written out as, NA2S2O3 + 2HCL + H2O (ranging from 25ml to 0ml in
