Compounds such as alcohols and glucose also contain hydrogen but are not categorised as acids. Describe an activity to prove it.
Answers
Answer:
Compounds such as alcohols and glucose do not dissociate in aqueous state and give hydronium ions.Hence,they are not categorised as acids.Hence,they do not conduct electricity.This can be demonstrated by a simple activity.
Explanation:
ACTIVITY.
Take some amount of glucose solution in a 100 ml beaker. Fix 2 nails on a cork and place the cork and place the cork inside the beaker. Connect the nails to the 2 terminals of a 12- volt battery through a bulb and a switch. Now, switch on the current. The bulb does not glow. This shows that glucose solution does not conduct electricity. The same effect is observed when the experiment is repeated with alcohol. This activity shows that chemical compounds like alcohol and glucose do not contain hydrogen ions although hydrogen is present in their molecule.
Answer:
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.
