phosphates and nitrates ) - which is when fertilizers < such as those on farms > can seep through the soil or even run down the soil - called runoff - into the creek causing the water to have more nutrients than it should. ) Depending on how much pollution there is depends on how much algae there is ( the more eutrophication -there is the more nutrients in the water- results in how much algae there will be.) We were also testing on the pH scale ( which measures the acidity or alkalinity of water ) goes from 0 - 14 where 6 - 0 is higher acidity and 8 - 14 is higher alkalinity ( alkalinity is what neutralizes/destroys acid. ) 7 on the pH scale is neutral and that is the ideal water for the ecosystem. The pollution that we were testing for is where the acid came from to begin with.

1. Introduction The objective of the experiments was to determine the identity of an unknown compound in order to properly dispose it. The process of disposal is very important when dealing with chemicals. Some chemicals are very

The algae comes from fertilizer that washes in the water from huge farms near the lake. The algae absorb a lot of oxygen from the water when they run out of steam and leave spots called “Dead Spots” which are areas where there is no oxygen so fish can’t breathe. Though this isn’t even the worst part, some of the bacteria that are in the algae get into our water and cause nondrinkable water. If someone were to drink it, they would get very sick and maybe have fatal outcomes. All hope is not lost though because Scientist are working very hard to solve how we can clean the lake.

Add sodium carbonate (Na2CO3), to the calcium chloride you already have. This will make calcium carbonate ( CaCO3), according to the formula: Na2CO3 + CaCl2 -> CaCO3 + 2NaCl. Afterward, filter this solution to obtain the calcium carbonate. Finally, heat the calcium carbonate at 248 degrees Fahrenheit to dry it out. Heat the calcium carbonate to 1,832 degrees Fahrenheit to get CaO.

Move 10 ml of the fourth well to the fifth well. FIll the fifth well with 90 ml of dh20 to reach 100ml. Start with 1% solution for Fluoride 100 ml and move 10ml of the first well into the next. Fill the well with 90ml dh20 to reach 100ml. move 10 ml of the second well to the third well.

Yasmin Givens Introduction The purpose of this experiment is to investigate the effects and results of agricultural runoff, as well as how varying types of fertilizer (conventional and time-released) may affect the ever-growing problem of eutrophication. If the conditions of agricultural runoff are simulated, then the algae will grow plentifully and consequently kill the other life in the water. If the different types of fertilizer are tested (conventional and time released), then the time released will be best to support and sustain the life in the simulated ecosystem. A major problem present today is agricultural runoff.

These techniques were used in the experiment to calculate atrazine and metalaxyl's logKOW and HOMO-LUMO ΔE values by creating calibration curves, calculating octanol-water partitions, and finding the EC50 (effective-concentration) of the ecotoxicity assay. Meanwhile, computational methods that were relevant to this experiment included HOMO-LUMO ΔE analyses on WebMO and referencing ChemSpider for predicted and literature logKOW values. It is important to note the controls that were used during this experiment; for the spectrophotometry, blank cuvettes and dark controls were used to ensure the accuracy of the absorbance and fluorescence data. Meanwhile, for the algae assay, the use of algae controls without pesticide provided a baseline for how much the algae grew without any pesticide. The species of algae (Pseudokirchneriella subcapitata) used and the conditions the algae were kept in (incubation and freezing) were universal for all ecotoxicity

After this was completed, we began to construct a constancy table. Group 1 was the smallest group on the constancy table as it only had two species: Globular algae and Filamentous algae. These two species of algae are

Most purchased product/service: Bleach • Clorox bleach to be specific, I use it for laundry and household purposes and it is a frequently purchased item of mines. It doesn’t matter what store I’am shopping in, if they have Clorox brand, I’m sure to grab a bottle. • Consumer behavior in this circumstance is the study of my actions while “searching for, purchasing, using, evaluating, and disposing of” Clorox Bleach, which I “expect will satisfy a certain need,” clean white laundry and disinfect household germs. • Targeting methods use by Clorox marketers are exceptionally placed, they seem to follow me everywhere I go.

It would probably take more time cleaning the entire pool than the actual leisure time of enjoying it. Imagine scrubbing a large pool. Cleaning it free from the smallest granules of dust, from growing algae, to marble-sized fruits just by yourself. That would take a lot of your precious time.

3. Results and discussion 3.1. Coagulation performance of CB[8] for HA removal The effect of the CB[8] dosage on HA coagulation in the absence of added salts in the synthetic water (fresh water) was investigated at pH 7.5. When the CB[8] dosage was less than 0.2 mmol/L, flocculation was not observed during coagulation. The HA removal efficiency was less than 50% (Fig. 1a).
