The melting point of the unknown was determined to be between 90-110 degrees. Based on the melting point we identified the identity of the unknown as Acetanilide. Acetanilide is an odorless, white flake solid or crystalline powder (pure form) which is soluble in hot water alcohol, ether, chloroform, acetone, glycerol, and benzene. Acetanilide is used as an inhibitor of peroxide sand as a stabilizer for cellulose ester varnishes. Acetanilide is also used as an intermediate for the synthesis of rubber accelerators, dyes, and is used as a precursor in penicillin synthesis.
The ground water may become contaminated with both organic and inorganic substances which may include heavy metals like Cadmium, Chromium and Nickel, etc. (Christensen et al, 2001). Pharmaceutical wastes can cause cancer within human cells. (Krifa et al. 2013).Pharmaceutical companies sometimes place active chemicals and waste into groundwater sources, in which almost all of the groundwater may be untreated which most likely cause contamination.
Silver nitrate tested for 2o and 3o alkyl halides expected in dibromocholesterol and sulfuric acid tested for alkenes expected in cholesterol. Bromination had 68.8% yield, debromination 73.7% yield, and overall 53.3% of commercial cholesterol was recovered as synthesized cholesterol. For commercial cholesterol, dibromocholesterol, and synthesized cholesterol, melting points were 145.2-148.1oC, 109.0-110.1oC, 146.3-148.2oC and retention factor (Rf) values were 0.69, 0.80 respectively. Chemical tests confirmed expectations, though some alkenes were present in dibromocholesterol. The similar melting points of the synthesized product as compared to the literature value; and similar Rf values for commercial and synthesized cholesterol showed the purity of
This explanation can be demonstrated in table 3 also because the results of the reactions demonstrates that chloride reacted more by the color of the product compared to the color of chloride in the mineral oil. Also it also demonstrates that iodine is the weakest oxidizing agent because the results show that iodide didn’t change much from the color that it showed in the mineral oil. In example 6 we have shown the activity series for the halogens used in this
To prevent poisoning in both adult and children use safety locks on all cabinets, store food and chemical products in separate areas, keep medications out of sight, teach children about poisonous substances, and discard all old or outdated medications. 3. First aid for swallowed poisons is to have victim lay down, give victim lots of clear liquids, treat for shock, and seek medical attention 4. First aid for inhaled poison is to call 911 and poison control center, put unresponsive victim in recovery
Conversely, Chemical plants can contaminate the pure water or create harmful diseases to humans and the Earth. The West Virginia chemical spill demonstrates the dangers chemical plants pose to our environment, and it is important to understand the devastating
Cadmium is a ubiquitous heavy trace metal toxicant and is well known as an industrial pollutant. Exposures to cadmium have been reported to reduce male fertility. Chromium is an important heavy metal which possesses several industrial applications Occupational exposure to chromium leads to alteration of semen status and may adversely affect the reproductive success of exposed workers. Lead is the most significant toxin of the heavy metals. Industrial decisions, such as the addition of lead to paints, dyes, and gasoline, have created an epidemic of lead poisonings.
Allergic reactions and anaphylaxis are a known side effect of many vaccines that are administered to humans. Anaphylaxis is a severe, multi-organ system reaction that can be life threatening. Anaphylaxis symptoms cause fever, swelling of throat and tongue, and shock. There are six types of vaccines that have caused anaphylaxis, including MMR, varicella zoster (chicken pox), influenza, hepatitis B, meningococcal, and tetanus containing vaccines. The varicella vaccine is known to cause the serious side effects in humans with immunodeficiencies, these side effects include infection after vaccination, pneumonia, encephalitis, and meningitis (Mercola, 2011).
