Poliovirus is from the subgroup enterovirus and the family Picornaviradae. It is a virus that causes poliomyelitis‚ which is better known as polio. Poliovirus is usually contracted by the fecal-oral route‚ but sometimes infects by the oral-oral route. Once ingested‚ it is thought that poliovirus first infects the epithelial cells in the mucosa of the gastrointestinal tract and then spreads to the submucosal lymphoid tissue. This is when the first mild symptoms of poliomyelitis occur. These symptoms

is titrated against a standard solution of a substance that will oxidize or reduce the unknown. In the present experiment you will take a sample containing iron‚ add acid to dissolve it [thereby converting all the iron to iron(II)]‚ then use a solution containing permanganate ion‚ MnO4-‚ to oxidize this Fe2+ to Fe3+ ion. The percent of iron in the sample will be calculated from the amount of permanganate needed to oxidize fully all the Fe2+ ions. A solution of permanganate ion in sulfuric

Experiment 1: Observations of Chemical Changes Abstract: In the lab 1 experiment‚ the objective was to observed properties of various chemical reactions between twelve different basic compounds. Each reaction revealed chemical properties consisting of color change‚ CO2 gas formation‚ and/or precipitate formation. Certain reactions made it possible to distinguish between an acid and a base. Through the results of this experiment‚ chemical properties observed in the reactions could be used to associate

In the Industrial Revolution‚ humans—western Europeans at first—learned to exploit coal and steam energy to mass produce goods with machines and to sell them worldwide. The Industrial Revolution began with production of textiles and eventually spread to other areas of manufacturing‚ as well as to farming and food processing. In the later nineteenth century‚ industrialization occurred on a large scale in metallurgical‚ chemical‚ and electrical industries. Once begun‚ it could not be stopped. The Industrial

Examination of Water and Wastewater 5210 BIOCHEMICAL OXYGEN DEMAND (BOD)*#(1) 5220 CHEMICAL OXYGEN DEMAND (COD)*#(2) 5220 A. Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods Section 5220B‚ Section
