PP025 - Oxidation of alcohols to aldehydes using dichromate(VI)
In this activity, a primary alcohol (ethanol) is oxidised to an aldehyde (ethanal) using an acidified dichromate(VI) solution. After collection by distillation, the organic product can be tested to co..

PP117 - Testing for organic functional groups: the iodoform reaction
Many 16+ curriculums include testing for organic functional groups. The iodoform reaction is a simple test for the presence of the acetyl (ethanoyl) group (CH3CO–). The reaction can also be used to te..

PP012 - Testing for carbonyl compounds with Tollen's reagent
Although both aldehydes and ketones contain the carbonyl functional group (-C=O), only aldehydes (or reducing sugars) give a positive ‘silver mirror’ test result with Tollen’s reagent. This small-scal..

GL247: The shelf-life of chemicals
The ‘shelf-life’ of a reagent depends on its chemical properties, how it is stored and how frequently the container is opened, thus exposing the reagent to air, moisture and other contaminants. Over t..
