Pentaaminechlorideocobalt (III) Chloride Heaven Lin and Forest Lin W.M. Keck Science Department‚ Claremont McKenna‚ Pitzer‚ and Scripps Colleges 925 N. Mills Avenue‚ Claremont‚ California 91711 Abstract Through using the spectrometer and titrations‚ the amount of the coordination compound‚ pentaaminechloridocobalt (III) chloride‚ was determined through a synthesis through an oxidation reduction of cobalt (II) chloride hexahydrate (CoCl2·6H2O) and a reaction of the product with ammonium chloride (NH4Cl) and ammonia

Draw and label 3 plant cells. * After a few minutes draw out the sodium chloride solution with a piece of filter paper placed at the edge of the coverslip. Replace it with distilled water added at the other side of the coverslip. QUESTIONS 1 Describe the cells in distilled water. How are the cells in 5% sodium chloride different from this? Describe what happens when you take away the sodium chloride solution and

Lab experiment 12 Percent of water in a hydrate The goal of Experiment 12 was to learn how to calculate the percent of water (by mass) in barium chloride and an unknown hydrate salt‚ as well as properly calculating the water of crystallization for the unknown hydrate salt. A hydrate salt is composed of anions (-) and cations (+) surrounded by a fixed number of water molecules‚ called water of crystallization. The hydrate decomposes upon heating and

matter. Introduction Sugar and salt look so similar that most people cannot tell them apart without tasting them. Chemically‚ white refined table sugar‚ sucrose‚ and salt are very different. An ionic bond between a positive sodium ion and a negative chloride ion creates a molecule of sodiumchloride (NaCl). Covalent bonds between hydrogen‚ oxygen‚ and carbon atoms form to form a sucrose molecule (C12H22O11). Ionic bonds form when oppositely Figure 1: The pile of white grains on the left are ordinary crystals

Milk of Magnesia is a combination of magnesium salt and such as magnesium chloride (MgCl2)‚ with sodium hydroxide (NaOH). The magnesium chloride and sodium hydroxide react to produce sodium chloride and magnesium hydroxide‚ which settles out of solution as a precipitate. Here the manufactures would separate the sodium chloride and magnesium hydroxide. They would be left with magnesium hydroxide as would leave the sodium chloride as a waste product .This is classified as a Double Displacement reaction

synthesize Sudan-1‚ preparation of phenyldiazonium chloride solution and β- naphthol solution were done. Ingrain dyeing was also done in this experiment. The synthesis of Sudan-1 has a two-step reaction – diazotization and coupling reactions. Diazotization is the formation of diazonium salt‚ meanwhile‚ the coupling reaction took place when an activated aromatic compound‚ β-naphtol was reacted with the diazonium salt‚ benzene diazonium chloride‚ to form the azo compound known as the 1-phenylazo-2-naphthol

Aqueous Solutions Reactions‚ Metathesis (Double Replacement) Reactions and Net Ionic Equations Terrance Shelton Introduction India’s cultural treasure and biggest tourist attraction is slowly losing its magnificent appeal due to decades of acid rain. The walls of the Taj Muhal are composed of a marble-like substance ( CaCO3) that corrodes and eventually crumbles when reacted with acid rain(H2SO4). Not only is the Taj Muhal suffering‚ but also other historic landmarks across the world. This is

Synthesis of DEET Abstract: For this experiment m-toluic acid was reacted with thionyl chloride resulting in a nucleophilic acyl substitution which could then be used to create DEET with excess diethyl amine (Figure 1). This was done by adding diethyl amine drop wise using a seperatory funnel which resulted in a gas formation which was controlled with a condenser attached to a gas vacuum. The resulting mixture was then washed to remove excess acids and bases and rotovapped. DEET was synthesized

understand electrolysis‚ you need to know what an ionic substance is. Ionic substances form when a metal reacts with a non-metal. They contain charged particles called ions. For example‚ sodium chloride forms when sodium reacts with chlorine. It contains positively charged sodium ions and negatively charged chloride ions. Ionic substances can be broken down by electricity. Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric current
