an inorganic compound represented by the formula AgI that is used in cloud seeding‚ photography‚ and can also be used as an antiseptic. These are the three main ways the compound has been used throughout the history of the world. While the compound remains to be used there have been a few concerns raised that the compound silver iodide may be toxic to humans and other organism. This paper will discuss the uses of silver iodide‚ whether or not the compound is toxic‚ and the compound itself discussing

When the pH of the mobile phase is equivalent to pKa value of analyte‚ the compound is half ionized. If the pH is 1 unit away from the pKa value of analyte then the change in the extent of ionization is around 90%‚ If the pH is 2 units away from the pKa value of analyte‚ the change in the extent of ionization is around 99%‚ If the

Selenium and cancer therapy In the article “Selenium Compounds‚ Apoptosis and Other Types of Cell Death: An Overview for Cancer Therapy”‚ Author Carmen Sanmartin‚ Daniel Plano‚ Arun K‚ Sharma and Juan Antonio Palop point out thtat Selenium (Se) is an essential trace element and can cause several types of cell death. Thus‚ it influences positively on many biological functions in human beings and animals. It is important in cancer treatment and prevention. At the beginning of the article‚ the authors

organic substances are impure and require techniques in order to purify a sample. One of these techniques to make an impure sample pure is by recrystallization. This experiment includes the determination of a good solvent for recrystallization for compounds such as: acetanilide‚ acetamide‚ aspirin‚ benzoic acid‚ naphthalene‚ and sucrose‚ for solvents such as: water‚ ethanol‚ benzene‚ and ethyl acetate. Also pure acetanilide is achieved. here are five major steps in the recrystallization process: dissolving

crystallization of a particular compound? What is the primary consideration in choosing a solvent for crystallizing a compound? volatile in order to be easily removed from the purified crystals. In selecting a solvent consider that like likes like. Polar compounds dissolve polar compounds and non-polar compounds dissolve non-polar compounds. Solvent will dissolve a large amount of the impure compound at temperatures near the boiling point of the solvent the compound would be completely insoluble in

synthesis includes two or more substances‚ which will then turn into one compound‚ usually being a more complex substance. The formula for synthesis is A+B → AB‚ and an example would be 2Na+Cl2 → 2NaCl. Another good example to better understand is two simple substances‚ such as hydrogen and oxygen can yield a more complex substance → water. Combustion has reactants of: metal and oxygen‚ nonmetal and oxygen‚ and a compound and oxygen yielding either the oxide of the metal‚ the oxide of the nonmetal

Introduction: In this lab‚ we measured the acid-base strengths of seven separate organic compounds. The lab was painless to perform‚ it consisted of adding a small amount of one of the organic compounds to a well‚ and testing the pH via testing paper. The color of the paper was then analyzed to determine what the pH of the compound was. The structures were benzenesulfonic acid‚ benzoic acid‚ benzyl alcohol‚ benzylamine‚ p-cresol‚ and p-toluidine. My initial hypothesis about the acidity/basicity
