Question

Compounds such as alcohols and glucose contain hydrogen but are not ` categorised as acids Describe an activity to prove it with neat labelied diagram.`​

Answer 1

Answer:

Activity: To show that

alcohols and glucose are not acids.

Materials required:

Dilute solution of ethanol and glucose solution Apparatus required : Beaker (1), carbon electrodes (2), dry cells (2),

bulb 1.5 V (1),

Explanation:

Procedure: Take a beaker and place two carbon electrodes into it. Connect the electrodes to a battery bulb through a key and a dry cell. Pour ethanol into the beaker and press the key. See, if the bulb glows. Bulb does not glow. Repeat similar experiment with glucose solution. Record your observations

Observation : It is observed that the bulb does not glow With both the solutions. Conclusion : The solutions of glucose and ethanol are non-conductors of electricity. Explanation: Ethanol and the solution of glucose containing hydrogen in their molecules do not conduct electricity. Therefore, these compounds do not

produce ions in solutions. Hence these are not categorised as acids.

Answer 2

Explanation:

Take the solution of dilute hydrochloric solution and glucose. Two nails are fitted on a cork and are kept it in a 100 mL beaker. The nails are then connected to the two terminals of a 6-volt battery through a bulb and a switch. Dilute HCl is poured in the beaker and current is switched on. Now, the Same experiment is performed with a glucose solution and an alcohol solution.

We will observe that the bulb glows in HCl solution and does not glow in the glucose solution.

Because: HCl dissociate into H + (aq) and Cl -(aq) ions. These ions conduct electricity in the solution resulting in the glowing of the bulb. On the other hand, the glucose solution does not dissociate into ions. Therefore, it does not conduct electricity
