Cu(II),Ni(II), have been synthesized by Pallavi et al, 2014 , and then evaluated for their antimicrobial activity.These compounds were potent and showed significant anti microbial activity.and also in the field of medicinal,organic and in organic chemistry Anti tubercular…

Selenium: The Essential Element Introduction Over the years, selenium is known to be the essential element in all forms of life. Selenium is a metalloid belonging to the block p, group 16, period 4. It is a gray metallic rare element widely distributed within Earth’s crust which has an atomic number of 34 and a symbol “Se”. Selenium was discovered in 1817 by Jöns Jacob Berzelius and Johan Gottlieb Gahn after analysing an impurity contaminating the sulphuric acid being produced by a factory…

capability to form inclusion complexes with the guest molecules i.e. poorly water soluble drugs. The formed inclusion complex shows significant changes physicochemical properties of drugs with respect to its solubility and dissolution rate. 2.1.2. Chemistry of cyclodextrins Structural features Three major CDs are crystalline, homogeneous, non-hygroscopic substances, which are torus-like macro-rings built up from glucopyranose units. The a-cyclodextrin (Schardinger’s a-dextrin,…

How the changing mass of solute effects the heat given out when dissolved in water Aim To investigate how the changing mass of a solute will affect the energy given out. Introduction Dissolving is when a solute is mixed into a solvent to form a solution. Dissolving can be either endothermic or exothermic. Endothermic reactions happen when the energy given out when bonds are broken, is greater than the energy given out when bonds are made. As more energy is used and taken in, the surroundings…

The purpose of this experiment is to observe the difference between ionic and molecular compounds using conductivity as a means of analysis. This lab will allow us to organize compounds based on the magnitude of their conductivity. This will allow us to determine whether or not a compound is molecular or ionic based on its conductivity. This lab also will determine the effect of concentration on conductivity of certain electrolytes, as well as the number of ions. We also will examine the effect…

dangerous situations, even though they are not proven to increase our probability of a specified event. George Gmelch and Richard Felsen released an article pertaining this subject. The article, entitled “Can a Lucky Charm Get You Through Organic Chemistry”, gave the general public a somewhat easy-to-read article, which provided an experimental result about how many people believe in magic and what they believe about it. By analyzing the article, it can be seen that the experiment covered…

THE EFFECTS OF OSMOSIS INTRODUCTION Osmosis is the process where molecules of a solvent are prone to pass through a semi-permeable membrane, going from a less concentrated solution to a higher concentrated solution. Doing this equalizes the concentrations on both sides of the membrane. Our question throughout the experiment was; What effects do the different concentrations of sucrose have on the rate of osmosis? The hypothesis was; If the solute concentrations do effect the rate of osmosis,…

The experiment was done to reveal how workouts supplements like C4 can affect the development of humans. Other experiments like this one can also be used to show how some substances may affect the development of humans. In the experiment the independent variable was the amount of the C4 that was placed into each well in the experiment, and the dependent variable was the zebrafish embryos after they were exposed to the C4. In addition, 2 controls were set up, containing a ocean/embryo solution…

Communication /6 Problem #2 Use the chart you just created to answer the following questions. a) Which substance would be the most corrosive? /1 Sample number 2 is the most basic and corrosive substance between the four samples. With its very high pH of 12, it can be predicted that sample number 2 is the oven cleaner that contains Sodium Hydroxide. Sodium Hydroxide (NaOH) is highly corrosive due to its elements; the presence of oxygen and an electrolyte (Sodium – Na) cause corrosion, the…

when the word chemistry comes appears. With the subject of chemistry, people usually think of cool experiments such as making toxic chemicals and blowing things up; however, writing plays a very vital part as a chemist. Dr. John Leyba, the chemistry and biochemistry department head and professor at the University of North Georgia (UNG), was able to give an insight of writing in the world of chemistry. Earning a Bachelor of Science in Truman State University and a Ph.D. in Nuclear Chemistry from…
