Humic acid

The water bottle brand Poland Springs had mostly clear water, it was extremely transparent, except there was a very light gray tint to the water that was barely noticeable. Also, when the water was first poured into both warm and cool temperature test tubes, there were some air bubbles in the test tubes. However, after 2 days, the bubbles seemed to have disappeared from both test tubes in both environments. Within both environments there was evaporation, however, evaporation along with water…

Have you ever wondered witch pop has the most fizz. Well in this paper I will tell you what carbonation is. How you can do this experiment at home. I will be telling you some history about who envented carbonation. Carbonation is a really cool thing when you think about it. It takes about 2 minutes to make 12 cans of pop. Different chemicals are added to the water to remove any tiny particles plus kill any bacteria that might be in it. The water is also run through a series of special filters…

levels fluctuate from 6.0 before exercise, to 4.5 immediately after exercise, to 5.0 six hours after exercise. This informs Tracey that Max’s kidneys are working to level off his pH to normal levels over time. During exercise, the body produces lactic acid, a waste product which causes the pH to drop. The kidneys release more hydrogen ions which cause the pH to decrease and make urine more acidic while the blood becomes more basic. After exercising, the kidneys don’t release as many hydrogen…

Purpose This lab’s purpose was to experiment how much of a syrup solution would seep through a dialysis bag at different temperatures. Procedure We prepared by filling up three dialysis bags with about 100 mL of a syrup solution. We tied knots on either end and measured the initial mass of the bags. The bags were measured in grams. Then we added water to three different beakers, each being a different temperature. One beaker was room temperature, another was heated to about body temperature…

Water quality of Freshwater Creek Abstract: This report will be detailing the results found after testing three different water quality parameters on water samples taken at Freshwater Creek and comparing them with past results. It will determine if Freshwater Creek is, has been or is becoming polluted. The three tested parameters were dissolved oxygen, biochemical oxygen demand and ammonia. What was found is that the results for all three tests fitted within the recommended guidelines for…

time. One of the disorders that can be seen if the homeostasis fails to occur is the acid-base balance. For a person to be in a good health, the maintenance of acid and base should be balanced in the body which is an essential function of the body in the biological process. The most important aspect in the prevention…

This size difference is suggested to be a consequence of the isoenzymes having different amino acids in the binding pocket of the active site. Histidine-200, histidine-67, and valine-62 in the active site of CA-I appeared to be the main amino acids which could potentially sterically hinder PTS. Further investigations, revealed that histidine-200 of CA-I sterically clashes with PTS, and this may significantly decrease the…

1. If the molarity of the NaOH solution is increased, it would take less drops to observe a colour change. A higher concentration lowers the amount of solution required to produce a reaction due to the presence of more molecules and a higher frequency rate, therefore less of the substance is needed to cause an equilibrium shift. 2. When you add 6.0 M NaOH into the iron (III) thiocyanate ion equilibrium system, the concentration of Fe+3 ion decreases. This causes the equilibrium to favour the…

As you can see, the data recovered from this experiment is very unusual. This is the interpretation and analysis the experiment regarding the cleaning power of the chlorine bleach produced by Clorox and laundry detergent produced by Oxiclean. This interpretation is essential to understand the data and how effective each of the independent variables in this experiment are. As an analysis, there were many key points that made this data relevant. Regarding the coffee, both of the cleaners did quite…

Purpose: The purpose of this experiment was to illustrate how to determine the density of a liquid and regulate volumetric glassware properly. To determine the mass of liquids using a scale, the density of water and (unknown) liquid D were weighed, inside of a volumetric flask. Once the mass was determined in grams, the density was easy to determine, by using the density equation. The second portion of this experiment was to calibrate a 10mL pipette. Once the density was determined for this…
