Question

Compounds such as alcohols and glucose also contain hydrogen but are not categorised as acids.

Describe an activity to prove it.​

Answer 1

Observations:

The bulb glows in HCl solution only. The reason is that HCl solution into H

+

and Cl

–

ions which help to conduct electricity while glucose and alcohol solutions do not dissociate into ions and so, do not conduct electricity. That is why we find the bulb glowing in HCl solution only.

Conclusions:

The above activity proves that all acids contain hydrogen but not all compounds containing hydrogen are. Due to this reason compounds such as alcohols and glucose although contain hydrogen, but they are not categorized as acids.

that above picture will also define that

hope it helps

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
