Analytical chemistry Analytical chemistry is the branch of chemistry that deals with the separation‚ identification and determination of components in a sample. Analytical chemistry can be divided into two branches‚ qualitative and quantitative. Qualitative analysis It deals with the identity of the constituents that are in an analytical sample. Quantitative analysis It deals with the determination of how much of a given substance is in the sample. The quantitative analyses are classified

sand and water * salt and water * sugar and salt * Due to the fact that mixture are not chemically combined‚ They can easily be separated into component substances by using physical means. Chemists have devised numerous methods for separating mixtures based on there differential physical characteristics Below are a couple of separation techniques: 1. Sublimation. This involves heating a solid until it passes directly from the solid phase into the gaseous phase. The reverse process

non-polar compounds and as starting materials for the synthesis of wide range of organic compounds. Chlorine containing antibiotic‚ chloramphenicol‚ produced by soil microorganisms is very effective for the treatment of typhoid fever. Our body produces iodine containing hormone‚ thyroxine‚ the deficiency of which causes a disease called goiter. Synthetic halogen compounds‚ viz. chloroquine is used for the treatment of malaria; halothane is used as an anaesthetic during surgery. Certain fully fluorinated

nitrogen and halogens – elements that are most of the time the only ones involved in organic compounds. The experiment focused on the Sodium Fusion test‚ which tested for all elements except oxygen. In the test‚ the test compound is broken down into its elements‚ which then bond individually with sodium. The presence of sulfur was tested either with lead acetate or sodium nitroprusside. The presence of nitrogen was tested with ferrous ammonium sulfate and potassium fluoride. The presence of any halogen
