Premium Copper Sulfuric acid Smelting
EXPERIMENTAL PROCEDURE: 1. 2.07 g of the mixture of naphthalene and benzoic acid was weighed accurately on a balance. The mixture was then dissolved in 40 ml dichloromethane and the solution was poured into a separatory funnel. 2. 20 ml of aqueous sodium bicarbonate solution was added to the dichloromethane. A stopper was placed on the separatory funnel and was shaken and pressure was frequently released. The 2 liquids separated into clear layers and the lower layer (dichloromethane layer) was

Experiment #1: Separation of Acid‚ Base‚ and Neutral Compounds from a Solid Mixture by Liquid-Liquid Extraction Introduction Liquid-liquid extraction is a technique used to separate chemical substances in order to purify or identify the various components of a mixture. Flavors‚ spices‚ perfumes‚ and medicines are just some of the everyday things that are extracted from plants and other natural sources [1]. The basic principle used to carry out this separation is the mixing of two liquids that are

Several years ago‚ Acme Mineral Extraction Company introduced teams in an effort to solve morale and productivity problems. Acme used highly sophisticated technology‚ employing geologists‚ geophysicists and engineers on what was referred to as the brains side of the business‚ as well as skilled and semi-skilled labor on the brawn side to run the company’s underground extracting operations. The two sides regularly clashed‚ and when some engineers locked several operations workers out of the office

Abstract This experiment focused on extracting and separating pigments of Chloroplast. For the procedure green leaves were grinded in a mortar with some chemicals and the fluid was filtrated to use for further analysis. Stripes of this solution were put on a filter paper and later‚ after dried placed into a beacon of solvent. After this the chloroplast pigments were separated by the solvent into groups of more or less soluble pigments. Aim How many pigment types are present in a green leaf? It

mixtures of the required mineral and unwanted material‚ and‚ being mixtures‚ they have variable composition. Measurement of the yield from a particular ore body is extremely important in the mining and minerals industry because it determines whether extraction of the metal from that ore is profitable or not. Whenever a new ore body is found‚ samples must be analyzed to determine the likely yield of the metal from it‚ and hence to decide whether it is economically worthwhile to mine and process the ore
