A pungent smell will be given off 28 of 43 test for sulphate ions add barium chloride solution if present a white ppt will form 29 of 43 halide ions make a solution in dilute nitric acid and add silver nitrate solution 30 of 43 Cl- white ppt, soluble in conc and dilute ammonia 31 of 43 Br- cream ppt, soluble in concentrated ammonia 32 of 43 I- yellow ppt, insoluble in both conc and dilute ammonia 33 of 43 test for iodine add a few drops of starch to the solution, the solution of will turn blue-black 34 of 43 burning of hydrocarbons sooty flame; high carbon content 35 of 43 test for alkenes add bromine water, after shaking the aqueous layer will decloursie 36 of 43 burning of alcohols clean blue flame indicative of complete combustion, sooty flame if incomplete combustion 37 of 43 reaction of alcohols SODIUM- solid disappears, mixture warms up, fizzing. PHOSPUROUS PENTACHLORIDE- solid disappears, misty Fumes, mixture warms up, hissing noise 38 of 43 oxidation of alcohols primary and secondary alcohols with acidified potassium dichromate solutions changes from orange to green when heated, change in smell 39 of 43 reaction of Group II metals with WATER Mg - few bubbles produced slowly, metal dulls. Ca - fizzing, mixture warms up, metal falls and rises, metal disappears, white solid produced. 40 of 43 reaction of Group II metals with HCL metal disappears, fizzing mixture warms up. 41 of 43 reaction of Group II metals with H2SO4 Mg-metal disappears, fizzing , mixture warms up. Ca-fizzinf initially but reaction stops. 42 of 43 reaction of Group II metals with OXYGEN Mg- bright white light to form a white powder. Ca- brick red flame to form a white powder. 43 of 43
