The paper disc (6mm diameter, whatman no.1 filter paper) containing various concentrations of samples 5-20ug/ml was chosen and placed aseptically on the agar surface with the help of a sterile forceps and paper discs were pressed slightly with the forceps to make complete contact with the surface of the medium. The plates were kept at room temperature for half an hour and subsequently incubated at 370C and observed for zone of inhibition after 24 hours. The inhibition zone around each disc was measured in millimeter. The results were recorded by measuring the zone of growth inhibition surrounding the

Hydrochlorimetry Lab Essay
1866 Words | 8 PagesThe purpose of this lab is to observe the reaction between hydrochloric acid and magnesium metal. When the substances are reacted over water, the products produced are a salt in aqueous solution and a gas. While the salt remains in the water as part of a solution, the gas produced will float to the top. Though water vapor pressure will affect the pressure of the gas in the eudiometer, it is possible to apply Dalton’s law of partial pursues to find the dry pressure of the gas. When the dry pressure is determined, the volume of the gas at STP can then be determined and what the experimental volume of one mole of the gas would be at STP.
Chemical Reaction Lab Report Essay
68 Words | 1 PagesPurpose: To recognize the evidence of a chemical change and to prove the law of conservation of mass by observing a series of chemical reactions involving copper. A specific quantity of copper will be transformed through a series of chemical reactions to form new substances and then recovered as solid copper. A percent yield will be calculated to determine the amount of copper recovered from the chemical reactions.
Oxalate Lab Report
3518 Words | 15 Pages1.0 Introduction Oxalates which refer to any salt or ester of oxalic acid are common constituents of plants and are found in the majority of plant families. They occur either as free acids, soluble salts of potassium, sodium and magnesium and the insoluble salt of calcium. The amount of oxalates in plants ranges from a few percent of dry weight to up to 80% of the total weight of plants. (Garcia-Fernandez et al., 2014) The amount of oxalates in plants ranges from a few percent of dry weight to up to 80% of the total weight of the plant.

The melting point of the pure ASA crystals were calculated in order to calculate of absorbance. Iron (III) salicylate dianion must contain the acidified solution Fe3+ in order to measure the absorbance values. The level of the impurity can
Ropivacaine Analysis
2122 Words | 9 PagesMust be considered as a local anesthetic any substance placed in contact with the nerve fibers, their origins or their endings, is capable of specifically and temporarily suspend their operation. Local anesthesia was discovered in 1880. The early substance used was cocaine. One significant concern with cocaine, however, was its capacity to be addictive. Extracted from the leaves of coca Erythroxylon by Scherzer in 1850, and then synthesized in 1860 by Niemann, cocaine is the first Local Anesthetic discovered.

Informative Essay On Ox513a
661 Words | 3 PagesZika virus has made it’s way to the U.S. after starting out in Central and South America. Mosquitoes are the carriers of the virus which causes a problem for many that live in the Southeast United States and specifically in Miami Florida since there is an abundance of the nasty blood suckers there. Scientist however may have found a way to stop the spread of this disease a new genetically modified mosquito called OX513A which I believe is the way that we will be to stop the spread Zika virus and here is why. Zika virus is an illness that is spread through mosquitos when they bite you. Many people that are infected with Zika virus will have no or very mild symptoms.

Synthesis Of Camphor Essay
1134 Words | 5 PagesIntroduction Camphor is the natural product of Camphora officinarum which mainly distributes in Asia especially in Japan and China.1Actually, since the dawn of civilization, this molecule has been known for its strong smell and the use of camphor has an extensive and long-valued history.2, 3 In ancient time, it was used for medical use in China and in Japan it was also applied in framework to make it lighter and in inks because of solubility in pigments.2-4 In Europe, it was applied to preserve wood and deterrent insect. Additionally, during outbreaks of some diseases in Europe such as Black Death and smallpox, camphor was used as a fumigant.3 Camphor was also used in ritual in India due to its nonirritant property.3 It is considered to be a molecule that changed the world because it is so multifunctional that strongly influences human’s life.2 Moreover, with the development of scientific research, the demand for camphor keeps increasing because camphor’s application is extended in many new fields including medicine
Silver Lining Research Paper
739 Words | 3 PagesThe ‘Silver Lining’ to Tooth Decay Tooth decay remains a thriving problem, to which an exemplary solution is yet to be discovered. Dr. Carla Meledandri and Dr. Don Schwass are in the works of developing what appears to be the ‘silver lining’ in the issue of tooth decay. Schwass’s envisioned a better approach to treating tooth decay, Meledandri’s expertise in the chemistry of nanoparticles bring that vision to life, giving way to a more promising future for teeth fillings. The pair proposes the concept of nanoparticles of silver (Ag) in miniscule concentrations display properties of more effective anti-bacterial effects relative to the current process of treating tooth decay. Schwass expresses his quest for the perfect solution was driven by
