Class 10 Science Practical Worksheet Pdf
Experiment No: ……5……
Objective: To study two physical and two chemical properties of acetic acid.
Requirements: Test tubes, Glass tubes (or dropper), Glacial acetic acid, ethanol, con. H2SO4, saturated solution of NaHCO3, lime water, etc.
Concepts:Molecular formula: CH3COOH
Structural formula:
Precaution:
Glacial acetic acid is corrosive in nature. It should be handled with care. Never inhale con. Acetic acid vapours
Questions:
Name the functional group present in acetic acid. Name the alkyl group present in acetic acid. State the IUPAC name of the acetic acid.
Why pure acetic acid is called Glacial acetic acid? (It’s FP is 16.60C / 289.6K. When it is cooled below
00C / 273K it forms white crystals like ice and hence it is called glacial acetic acid.) Give two reasons for calling acetic acid as “acid” (1. Litmus, 2. react with N2CO3) Why is one drop of con. H2SO4 added to the reaction mixture for esterification?
Acid acts as a catalyst
It also absorbs and removes the water formed during the reaction and makes the reaction proceeding in the forward direction only.
Why the esterification reaction mixture should not be heated on direct flame? / OR / Why one should not note try to note the smell of the mixture directly form the test tube?
(The reaction mixture can spurt and hence may cause serious accident.)
♦ Multiple choice questions
1. A student is asked to add a teaspoon full of solid NaHCO3 to a test tube containing approximately 3 mL of acetic acid. He observed that the solid NaHCO3
· Floats on the surface of acetic acid
· Remains suspended in the acid
· Settles down in the test tube
· Reacts with acetic acid and a clear solution is obtained.
2. Mohan added 5 mL of dil. ethanoic acid to 10mL of water in a test tube. After shaking the mixture he observed that
· A clear solution was observed
· A white ppt appeared in the test tube
· Ethanoic acid formed a separate layer at the bottom of the test tube.
· A colourless gas was evolved.
3. Which one of the following reagent gives brisk effervescence with ethanoic acid?
· Ca(OH)2
· NaCl
· NaHCO3
· NH4Cl
4. The chemical composition of lime water is ----------- and it is ------ in nature.
· CaO , acidic
· Ca(OH)2 , basic
· CaO, basic
· Ca(OH)2 , acidic
5. A student takes a small quantity of NaHCO3 in a dry test tube and pours 4 – 5 drops of ethanoic acid to it. What will he observe?
· Evolution of a colourless gas with pungent smell.
· Bubbles of colourless , odourless gas.
· Evolution of brown fumes along wit abrisk efferscence.
· Evolution of a colourless gas with bounce with a pop sound when a burning splinter is brought near it.
