A small amount of the unknown (approximately the tip of the spatula was used for all the pigments) was added into each clean dry test tube. For the first test 1 mL of 3 M of HNO3 was added. As soon as the acid came into with the solid‚ the pigment was observed to dissolve while also turning the solution into a pale clear colour. The same amount was used for the HCl reagent. As soon as the acid touched the pigment it yielded in a clear solution (solid dissolved after a few shakes). When the KI was

RECRYSTALLIZATION Group Medical Technology Organic Chemistry Laboratory ABSTRACT Recrystallization is one of the simplest and most widely used technique for purifying organic solids through the differences in solubility at different temperatures. It is also the process in which the solid to be crystallized is dissolved to either a hot solvent or a hot solvent mixture and is cooled in a solution.In this experiment‚ acetanilide‚ the crude product of acetylation of aniline and acetic anhydride

As the nation’s largest retailer‚ second-largest corporation‚ and largest private employer (with 1.3 million workers)‚ Wal-Mart made headlines this past year at an unprecedented rate. All too often‚ these headlines revolved around Wal-Mart’s infamous employment practices. While Wal-Mart isn’t the only big box store criticized for its policies‚ it has become a symbol for much of what is wrong with employers. Wal-Mart reported a net income of over $11 billion last year—surely plenty of money to remedy

Marie Alessandra T. Reyes Group 4 18L Quantitative Determination of the Acidity of Soft Drinks I. Introduction Soft drinks are well known beverages among the young that are consumed mostly for pleasure. These beverages normally contain flavoring‚ sweeteners coloring‚ carbonic acid and acids. Carbonic acid and acids play an important part in the formulation of soft drinks. They enhance the flavor and give a pleasant refreshing ’lift ’ to the drink. The type of acid used can even affect the palatability

CHEMICAL EQUILIBRIUM I. Introduction In a chemical reaction‚ when reactants are mixed together in a reaction vessel‚ the whole of the reactants do not get converted into products. After some time‚ there will come a point when a fixed amount of reactants will exist in harmony with a fixed amount of products; neither amount will change anymore. This state is called chemical equilibrium (Birk‚ 1994; Jones‚ 1987; LeMay‚ 2002). There are three characteristics of a system in chemical equilibrium: a
