1. Qualitative Analysis of Acetic acid…

2. Outlines Qualitative Analysis Steps in Qualitative Analysis General properties of Acetic Acid Preliminary Examination of Acetic Acid Procedure along with C.T Uses and Application of acetic acid

3. Qualitative analysis It is the determination of chemical composition of sample Kastle meyer test for blood Iodine test for starch (organic qualitative analysis) Flame test (Inorganic qualitative analysis)

4. Steps in qualtitative analysis

5. General properties of acetic acid Acetic acid got its name from ACETUM , which is a Latin word meaning VINEGAR. It is a colorless liquid compound with sour taste and pungent smell.

6. Preliminary test in qualitative analysis Physical state Color Flame Test Solubility Behavior Test of Unsaturation Detection of Element Test for Functional Determination of Melting point and Boiling Point Specific Test Conclusions

7. Apparatus Blue Litmus Paper Double bored cork Test Tubes Acetic Acid Delivery tube Thistle funnel Sodium bicarbonate Stand with clamp Distilled water Lime water Boiling tube

8. Procedure: Try the experiments below and observe the different properties of acetic acid in a real lab: Experiment Observation Inference Odour : Take a small amount of acetic acid Pungent smell irritating pungent smell in a test tube and detect its odour by wafting. Solubility in water : Take a small amount of A homogenous Acetic acid is water in a test tube and add a small amount solution is formed soluble of acetic acid to it and shake well. Effect on litmus :Take a small amount of Blue litmus turns red It is acidic in nature acetic acid in a test tube and dip a strip of blue litmus paper in it. Reaction with sodium bicarbonate : Take a small quantity of sodium bicarbonate solution A gas is evolved The gas produced is c in a boiling tube. Cork the tube with a double bore cork which turns lime carbon dioxide due and insert a thistle funnel into the tube. Then place water milky to the action of a boiling tube containing lime water near the tube CH3COOH on containing NaHCO3 solution. Insert one end of the NaHCO3 which turns delivery Tube into the tube containing NaHCO3 solution lime water milky. and the other end into the tube containing lime water. Now, add acetic acid into NaHCO3 solution through the thistle funnel and observe the change in color Of lime water

9. Confirmatory test Experiment Observation Inference 1Take 0.1g of salt in a china dish. Fruit odour confirms the presence acetate is Add 1 ml of ethanol an 0.2 ml of cons. H2SO4 of acetate ion. Confirm and heat. 2 Take 0.1g of salt in a test tube ,add 1-2ml , Deep red color appears which distilled water, shake well filter if necessary. disappears on boiling And a brown- red Add 1-2 ml neutral ferric chloride solution to the precipitate is formed. filtrate.

10. Uses Of acetic acid Acetic acid is used as a congulant in manufacturing rubber and is also used for the preparation of dye stuffs and perfumes. 2 . Acetic acid is used in solvent for inks , paints and coating. 3 . MEDICAL INDUSTRY: Acetic acid injections used to treat cancer as local irritant. 4 . It is used in different other compounds. 1 Ester 2 Alcohol 3 Vinyl acetate
