Introduction Extraction is a purification technique used in organic chemistry to separate compounds from a mixture of two or more compounds. There are three different extraction techniques: liquid-liquid extraction‚ solid-liquid extraction and chemically active extraction. All three types of extraction follow the same principle. Organic molecules dissolve in organic solvents and polar molecules dissolve in aqueous solvents. This phenomenon is observed because of the intermolecular forces between

Determination of Chemical Formulae: The Reaction of Zinc and Iodine By Sarah Abstract: The main objective of this experiment was to use to the reaction between zinc and iodine to examine the validity of the Law of Conservation of Mass and the Law of Constant Composition. The Law of Constant Composition was tested by determining the mass of each of the reactants‚ zinc and iodine‚ and comparing their total to the mass of the zinc iodide product plus the excess zinc. The total mass of the reactants

Flat Parsley or garden parsley (Petroselinum crispum) is a species of Petroselinum in the family Apiaceae‚ native to the centralMediterranean region (southern Italy‚ Algeria‚ and Tunisia)‚ naturalized elsewhere in Europe‚ and widely cultivated as an herb‚ a spice‚ and a vegetable. Where it grows as a biennial‚ in the first year‚ it forms a rosette of tripinnate leaves 10–25 cm long with numerous 1–3 cm leaflets‚ and ataproot used as a food store over the winter. Parsley is widely used

Communication in the workplace is essential for success. To increase understanding of a person’s personality and their work ethics the Myer’s Briggs Personaliyt Test was developed to assess a person’s psychlogical profile and give insight on how they relate to other people . This can be a good tool to determine compatibility in the workplace and give insight on how to communicate with a person. This paper will focus on my personality type‚ whether I belive this is an accurate assessment‚ give

Esters are present in a variety of common compounds‚ from fragrances to animal fat (McMurry‚ 2008). Although these esters can undergo many different important reactions‚ this lab is particularly interested in the hydrolysis of esters into carboxylic acids and alcohols.

These acids provide an acidic environment for reduction of ferric iron to ferrous (Fe2+). Ferrous iron can be absorbed in the body system. As in following equation of iron (iii) reaction with Ascorbic acid ‚ the product is iron (ii) chloride which is soluble 2 Fe3+ (s) + C6 H8 O6 (aq) → 2 Fe2+ (aq) + C6 H6 O6 (aq) + 2 H (aq)+
