Flame tests
•
Preparation of aldehydes using simple distillation and carboxylic acids by heating under reflux
•
Preparation of halogenoalkanes
•
Test for alkenes using bromine water and acidified potassium per manganate
•
Test for halide present in a halogenoalkane by warming with sodium hydoroxide dissolved in ethanol followed by dilute nitric acid (to neutralize OH) and silver nitrate followed by ammonia solution
•
Distinguish between aldehydes and ketones using Benedicts or Fehlings solution. Formation of red precipitate confirms aldehyde
•
Drawing apparatus for simple distillation, heating under reflux and seperation of two immiscible liquids (dropping funnel)
•
Test for sulfates, sulfites and carbonates using barium chloride solution

Reactions of group 2 and group 7 elements
•
Volumetric analysis: esp thiosulfate
•
Test for SO2, CO2, H2 and O2. (by sankait36): SO2 - turns acidified potassium dichromate(VI) from orange(Cr6+) to green(Cr3+), CO2 - turns lime water milky (due to insoluble calcium carbonate), H2 - test with burning splint, ignites with a pop sound, O2 - relights a glowing splint
•
Uncertainties (by sankait36): uncertainty = (maximum reading) - (minimum reading) / 2 , %uncertainty = (uncertainty / actual reading) * 100
•
In titration, discard the titre that is not concordant to 0.2 cm^3
