Accept/Reject = If this dirty water can be treated it will then be clean and drinkable water. It was confirmed “dirty” water it was dark brown and had a smell to it and it was not drinkable. After I filtered the dirty water it looks clean the dirt out of the water and now the water looks clean so it could be drinking. 3. What are the differences in color, smell, visibility, and so forth between the “contaminated” water and the “treated” water?
Task 1 M1 Describe the scientific principles behind each of the three procedure above. Vacuum filtration is a procedure when a sold needs separating from a solvent to react the mixture. Then the mixture of a solid is measured through the filtration paper in a Buhner funnel. The liquid is drained through the funnel into the flask. Equipment • Filter paper • Buhner funnel • Tubing • Clean solvent • Disposable dropper Method 1.
Abstract: I am doing this experiment to see what the safest water to drink is. This will help society to see what type of water the cleanest and safest water to drink is. I will take samples of all the water and grow bacteria from them to see which water has the least contaminants. Purpose: The purpose of this experiment is to compare different types of water, including, well water, city water, bottled water, and water from a water fountain. I plan to take tap water from multiple faucets, with some using well water and others using city, use a brand of bottled water, and samples from a water fountain to grow bacteria.
Copper chloride dissolve in aqueous solutions to give [Cu (H2O)6]2+ which has blue color, and yellow or red color of the halide complexes [CuCl2+x]x-. Concentrated solutions of CuCl2 are green due to the combination of these various chromophores. It's also considering as week Lewis acid and mild oxidizing agent. The aqueous solutions of copper(II) chloride is Green when high in [Cl−], but more blue when lower in [Cl−]. Parent acid and base: Hydrochloric acid HCl + Cu (OH) 2 Uses: *Can be used in organic synthesis as it effects chlorination of aromatic hydrocarbons, this is often performed in the presence of aluminium oxide.
Free chlorine is the chlorine available to sterilise the water and is usually represented by hypochlorous acid and hypochlorite ions. When a solution containing free chlorine is exposed to ultraviolet light both hypochlorous acid and hypochlorite ions are broken down as shown below: 2OC〖l^-〗_((aq.))+u.v.→2C〖l^-〗_((aq. ))+〖O_2〗_((g)) 2HOCl_((aq.))+u.v.→2HCl_((aq. ))+〖O_2〗_((g)) When chloramine is exposed to high-energy ultraviolet light, the Cl-N or Cl-H bonds will be broken. Then, shorter wavelength ultraviolet light (less than 230nm) will break down water molecules into hydroxyl radicals that will oxidize the chloramines rapidly.
However, each water source has its own unique chemical composition. My project, therefore aims to prove that the pH balance of each water source will change at different rates because of their own chemical composition after bleach and vinegar have been added in equal quantities to each source. Trends/patterns: There were the following patterns: The pH level stayed consistent when the test was repeated. Bleach raised the pH level of all water sources. Vinegar decreased the pH level of all water sources.
A table to show the pH of certain solutions Solution Test 1 Test 2 Test 3 Average Distilled water 7.7 7.9 7.8 7.8 2.5 g NaHCO3 (Sodium bicarbonate) 8.1 8.3 8.3 8.2 10ml of 0.85% lactic acid 3.1 3.2 2.9 3.1 5g NaHCO3 (Sodium bicarbonate) 8.1 7.9 8 8 Dry ice 4 4.1 4.2 4.1 Solid NH4Cl 6 6.8 6.5 6.4 0.1M HCl 2.5 2.4 2.3 2.4 Compare the increase or decrease of pH in different solutions to the pH of the distilled water. 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. In comparison to the average pH of the distilled water, the average pH of the lactic acid solution decreased significantly in pH. Similarly, acidosis is caused when there is a buildup

“Concentration is measured in moles (M) per cubic decimeter; it shows us how man particles there acre dissolved in a substance. Therefore, 1M of hydrochloric acid dissolved in one cubic decimeter of water is the same concentration as 1M of sodium chloride dissolved in one cubic decimeter of water. If the amount of moles per cubic decimeter doubles from 1M to 2M, then so does the concentration double? “ So as the concentration of HCL increases, the rate of the reaction decreases because of the amount of energy that is included in the reaction(it increases as the HCL concentration
