Quantitative and Qualitative analysis Ensuring accuracy in both quantitative and qualitative methods. Accurate data collection is essential in maintaining the integrity of research. Working accurately greatly decreases the possibility of an error occurring in an experiment‚ provides a greater chance of producing expected results and provides knowledge gained only from proven results. Quantitative methods generate numerical data or data that can be transformed into useable statistics. It is used

9-48 MICROBIOLOGICAL EXAMINATION (9000) 9221 MULTIPLE-TUBE FERMENTATION TECHNIQUE FOR MEMBERS OF THE COLIFORM GROUP* 9221 A. Introduction The coliform group consists of several genera of bacteria belonging to the family Enterobacteriaceae. The historical definition of this group has been based on the method used for detection (lactose fermentation) rather than on the tenets of systematic bacteriology. Accordingly‚ when the fermentation technique is used‚ this group is defined as all facultative

The yield of a metal from a particular mineral or ore is the mass of metal that can be obtained from a particular mass of the mineral or ore‚ and is often expressed as a percentage. It is possible to use formulae to calculate/predict yields of metals from particular minerals (pure compounds)‚ for ores we have to measure them experimentally. This is because ores are mixtures of the required mineral and unwanted material‚ and‚ being mixtures‚ they have variable composition. Measurement of the yield

Abstract Carbohydrates are the most abundant organic compounds in the plant world. They act as storehouses of chemical energy (glucose‚ starch‚ glycogen); are components of supportive structures in plants (cellulose)‚crustacean shells (chitin)‚ and connective tissues in animals (glucosaminoglycans); and are essential components of nucleic acids (D-ribose and 2-deoxy-D-ribose). Monosaccharides‚ oligosaccharides‚ and polysaccharides are theclassifications of carbohydrates. This experiment involves

The first polyurethane synthesised by Dr Otto Bayer‚ in 1937‚ at IG Farbenindustrie Germany‚ by the reaction of a polyester diol with a diisocyanate‚ opened a new way in macromolecular chemistry: that is the synthesis of polymers by a new reaction‚ called polyaddition reaction. Polyurethane (PUR and PU) is any polymer composed of a chain of organic units joined by carbamate (urethane) links. Polyurethane polymers are formed through step-growth polymerization‚ by reacting a monomer (with at least

An Introduction to Qualitative Analysis Purpose: Tests the ions of Mg2+‚ Ca2+‚ Sr2+‚ and Ba2+‚ and identify them separately. By using these observations‚ identify the unknown ion. Then tests the ions of SO42-‚ CO32-‚ Cl-‚ and I-‚identify them separately‚ and use the observation to identify the unknown. Procedure Part I - Qualitative Analysis of Group 2 Elements Mix 0.02M K2CrO4 with each Mg(NO3)2‚ Ca(NO3)2‚ Sr(NO3)2 and Ba(NO3)2 together. Secondly‚ mix 0.1M (NH4)2C2O4 instead
