The purpose of this lab was to investigate how the concentration of ammonia affects the formation of coacervates. It was hypothesized that as the ammonia concentration increase, so will the number of coacervates until it reaches the optimal state, then would start to decrease. For this experiment 4 mL of gum arabic solution (carbohydrate) was mixed with a gelatin solution (protein) and was placed under a microscope to observe the number of coacervates. According to Oparin, combining organic macromolecules

Table 2. Shows the 10 groups results of the rate of change in g/s with the average rate displayed along with the standard deviation. As shown the average rate is within negative 0.000293 and positive 0.001740. From this table we can confirm that there have not been outliers in the results, outliers could come down to the results of errors on the practical. These errors could be caused by incorrect use of equipment, fluctuations in the solution or difference in eggs used. At a zero concentration the

This experiment investigates the effect of stomach acid at different pH levels on the solubility of metformin hydrochloride tablets. According to my results, the metformin hydrochloride tablets dissolved at a faster rate in the simulated stomach acid with less alcohol, and therefore, more acidic. This conclusion, proves the hypothesis stated above. As predicted, the simulated acid with less traces of alcohol was a more suitable environment for the medicine to dissolve at a faster rate. Consequently

The pH of different liquids before and after they are filtered Problem Does filtering different liquids cause the pH to change? Hypothesis: The pH of the dirty water and the salt/bicarb soda/sugar water will change the most drastically when they are filtered. Aim: To investigate the effectiveness of a natural water filter on the pH of different liquids. Materials: • Green Science Clean Water Kit (includes plastic filter system, active carbon, sand, rocks, and filter paper) • pH Indicator

Problem: To discover what types of carbohydrates are in certain products Monosaccharides, disaccharides, or polysaccharide. Materials: The materials used are: Test tubes, Test tube holders, Glass marking pencil, benedict’s solution, Apple, Table sugar solution, I-KI solution, medicine dropper, hot plate, water, maple syrup solution, dextrose solution, envelope glue, monosaccharide solution, disaccharide solution, polysaccharide solution, and oats (cereal). Procedure: The procedure is: A. Known

composts are about to be in neutral pH within range from 6-8. However the initial pH of the manure compost will be more alkaline, with a pH as high as 8.5. Microorganism in compost will grow and multiply within the pH range from 5.5 to 8. The organic acids are formed in the initial stages of the aerobic decomposition process and these acidic conditions favor the growth of fungi

Sugar's effect on your health The average American consumes an astounding 2-3 pounds of sugar each week, which is not surprising considering that highly refined sugars in the forms of sucrose (table sugar), dextrose (corn sugar), and high-fructose corn syrup are being processed into so many foods such as bread, breakfast cereal, mayonnaise, peanut butter, ketchup, spaghetti sauce, and a plethora ofmicrowave meals. In the last 20 years, we have increased sugar consumption in the U.S. 26 pounds to

Will a bath bomb containing lime juice rather than citric acid dissolve faster? I think there is a chemical reaction within the bath bomb that makes it fizz, but I am not sure what things are reacting. I also think that if I substitute lime juice for citric acid in one half of the bath bomb, the half with citric acid will dissolve quicker. This is because it is pure citric acid, unlike lime juice which has other things as well as citric acid in it. Research Bath bombs are composed of several ingredients

whether cream of tartar, laundry detergent, and vinegar are neutral, bases, or acids. Introduction This experiment will discuss whether cream of tartar, laundry detergent, and vinegar are neutral, bases or acids contingent on changes in color. Neutral substances are chemicals that have no properties of either acids or bases, have equal parts hydrogen and hydronium ions and don't change the color of litmus paper or other acid-base indicators. A base is a chemical species that donates electrons or hydroxide

What is a ratio? A ratio is a way to compare and separate the values by dividing one value by the total. What is a chemical formula? A chemical formula is a way to show chemical symbols and numbers to represent a substance. Compare and contrast the properties of water with the properties of hydrogen and oxygen. Water, Hydrogen, and Oxygen have many similarities and differences. The similarities of the 3 are that they can be turned into a gas (gas state) by this water can turn into liquid by the
