level questions: PREPARATION OF BURROW'S SOLUTION
| Question | Answer |
|---|---|
| Test for Aluminum ion | A) Al³ + NH4OH → Al(OH)3 + NH4 forms gelatinous precipitate of aluminum hydroxide B) The precipitate formed in the presence of hydrochloric acid is caused by the creation of soluble aluminum chloride. Al(OH)3 + 3HCl → Al Cl3 + 3H2O C) Aluminum chloride from the solution reacts with ammonium hydroxide to form aluminum hydroxide precipitate, which absorb blue color from solution to form an insoluble complex AlCl3 + 3NH5OH → 3NH4Cl +Al(OH)3 |
| Test for Acetate ion | A) Acetate reacts with concentrated sulfuric acid and ethyl alcohol CH3COOH + C2H5OH → CH3COOC2H5 + H2O form ethyl acetate with a fruity smell and water B) Acetate react with purified water and ferric chloride (CH3COO)3Fe + H2O → (CH3COO)(OH)2Fe + 2CH3COOH |
| Pharmaceutical use of Burrow's solution | 1 Treatment for Ear infection 2 Astringent |
| Alternative methods in preparing Burrow's solution? | 1 Sodium acetate 2 Potassium aluminum sulfate |
| What was the compound formed when white or nearly colorless gelatinous precipitate was observed in the test for aluminum? | AL³ + NH4OH --> AL(OH)3 + NH4 formed a precipitate of aluminum hydroxide |
| Burrows Solution Synonym | Aluminum acetate solution |
| Aluminum acetate and glacial subacetate to form what | Burrow Solution CH3COOH3 + CH4H8AlO5 --> Al (OAc)3 |
