PP011 - Testing for carbonyl compounds with Fehling's solution
Click to download Document.
Although both aldehydes and ketones contain the carbonyl functional group (-C=O), only aldehydes give a positive test (formation of an orange to brick-red precipitate of copper(I) oxide) with Fehling’.. more

PP064 - Ammonia chemistry in a petri dish
Click to download Document.
A microscale activity which demonstrates a number of chemical reaction with ammonia. Because this is microscale, quantities of chemicals used are tiny,  making disposal and clearing up very easy.

PP012 - Testing for carbonyl compounds with Tollen's reagent
Click to download Document.
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.. more
