Compounds such as alcohols and glucose a | Class 10 Science Chapter Acids, Bases and Salts, Acids, Bases and Salts NCERT Solutions

Q6.

Compounds such as alcohols and glucose also contain hydrogen but are not categorised as acids. Describe an Activity to prove it.

Because glucose and alcohol do not dissociate into ions. Therefore these solution are not considered as acid -

Experimental verification :

Procedure : Two nails are fitted in a cork and they are kept in a 100 ml beaker. Then the nails are connected to the two terminals of the battery of 6 volt along with a bulb and a switch. Now some dilute HCl is added in the beaker and allows the current to pass through the circuit. The same experiment is carried out with glucose and alcohol solutions separately in place of HCl.

Observations :

The bulb glows only in HCl solution only. Because HCl solution dissociates into H+ and Cl ions which conduct electricity whereas glucose and alcohol solutions do not dissociate into ions and so, these solutions do not conduct electricity. So the bulb doesn't glow.

Interpretation :

Activity above hereby proved that all acids contain hydrogen but not all compounds that contain hydrogen are acids. Therefore compounds such as alcohols and glucose contain hydrogen, and are not categorised as acids.
