List out the materials required to test whether the solutions of given acids and bases contains ions or not. Explain the procedure of experiment.
Answers
Materials required:glucose, alcohol, HCl,NaOH, sulphuric acid, electrical wires, two graphite rods, beaker, 230volt AC plug, bulb.
procedure:
1.prepare solutions of glucose,NaOH, alcohol, HCl, H2SO4.
2.connect electrical wires to graphite rods separately in a 100 ml beaker.
3.connect free ends of the wire to 230volt AC plug and comlete the circuit by connecting a bulb to one of the wires.
4.test the solutions prepared with circuit prepared.
The bulb glows in the solution which contains ions.
The bulb glows only in acid and basic solutions it does not glows in alcohol and glucose solutions.
Acid and basic solution have ions and the moment of these ions in solution helps for flow of current through the solution.
Answer:
List of the material required
1) Glucose
2) Alcohol
3) Dil. HCL
4) Di H2.SO4,
5) Beaker
6) Connecting wires
7) 230 voltage AC supply
8) Bulb
9) Graphite rods
Procedure:
1) Prepare solutions of glucose alcohol, hydrochloric acid and sulphuric acids, etc
2) Connect two different coloured electrical wires to graphite rods separately in a 100 ml beaker.
3) Connect free ends of the wire to 230 volts AC plug and complete the circuit as shown in the figure by connecting a bulb to one of the wires. 4) Now pour some dilute HCT in the beaker and switch on the current.
5) We can notice that the bulb glows.
6) Repeat activity with dil. Sulphuric acid, glucose and alcohol solutions separately.
7) We will notice that the bulb glows only in acid solutions (in HCI and H,SO,) but not in glucose and alcohol solutions.
Conclusion:
All compounds containing hydrogen are not acids.
