The nails are then connected to the two terminals of a 6-volt battery through a bulb and a switch. Some dilute HCl is poured in the beaker and the current is switched on. The same experiment is then performed with glucose solution and alcohol solution. Observations It will be observed that the bulb g lows in the HCl solution and does not g low in the glucose solution. Result HCl dissociates into H+ and Cl− 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. Conclusion From this activity, it can be concluded that all acids contain hydrogen but not all compounds containing hydrogen are acids. That is why, though alcohols and glucose contain hydrogen, they are not categorised as acids.

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. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Featured image Select file Browse Click on image to update the captcha.
