What danger exists with the Tollen’s reagent?a) The silver mirror that forms is high reflective to lightb) ammonia used is very corrosivec) Tollen’s reagent decomposes on standing to an explosive substanceEquipment Preparation2. Test tube size is very important in performing functional group tests?a) true. The test tube must not become so filled with reagent and test substance, that it becomesdifficult to mixb) true. The test tube must be completely filled with the reagent and test substance, so that it canonly be mixed by stoppering and inverting the test tubec) falseReagent Preparation3.
