Gasometric method :- There are number of gas but only few gas are used as inhalant. Inhalant are the drug or chemical which are in vapour form are inhaled in the body. Some gas are used as anaesthetic. Inhalation of […]
SOLUTIONS PROBLEM IN GRAVIMETRY :- Process carried out in dilute solution. Reagents mixed slowly with constant stirring. Ppt carried in hot solution if stability permits Advantage of heating :- solubility is increases, reduction in degree of supersaturation, coagulation occur Crystalline […]
STEPS INVOLVED IN GRAVIMETRIC PRECIPITATION :- PREPARATION OF THE SAMPLE SOLUTION. PRECIPITATION PROCESS DIGESTION OR OSTWALD RIPENING FILTRATION WASHING DRYING IGNITING WEIGHING CALCULATION • SAMPLE SOLUTION :- sample solution is prepared generally dilute solution is preferred. Adjustment of the volume, PH, […]
Paper Chromatography :- Definition :- it is defined as a separation technique where separation of a mixture of compound is mainly achieved by a flow of solvent on a chromatographic paper. Stationary phase has a bound or abosorbed water present […]
Thin layer Chromatography (TLC) :- TLC is method of analysis in which the stationary phase is spread as a thin layer on a rigid supporting plate. The mobile phase a liquid is allowed to migrate across the stationary of plate. […]
Oxygen flask combustion :- Wolfgang schoniger is the chemist who first proposed this method in 1955. Oxygen flask combustion method has been used to determine of sulfur & Halogen in medicine. Apparatus :- The apparatus consists of heavy walled conical , deeply liped […]
Karl Fischer Titration :- Karl-fischer titration is method to use to determine amount of water content and moisture content in given sample. PRINCIPAL :- Karl-fischer titration is based on an iodine/iodide reaction means water is react with iodine. INSTRUMENTATION :- […]
