compound like alcohol and glucose also contain hydrogen but are not categorised as acid discuss an activity to prove it
Answers
Answer:
The nails are fitted in a cork and are kept in a 100 ml beaker. Then these are connected to the two terminals of a 6 volt battery along with a bulb and a switch. Now some dilute HCl is poured in the beaker and current is allowed to pass through the circuit. The same experiment is carried out using glucose and alcohol solutions separately in place of HCl.
Observations:
The bulb glows in HCl solution only. The reason is that HCl solution dissociates 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 acids. Due to this reason compounds such as alcohols and glucose although contain hydrogen, but they are not categorized as acids.
solution
Explanation:
Answer:
Take a beaker of 250 ml and place two nails fixed with the help of cork.
• Connect the nails to the two terminals of a 6 volt battery as shown in figure.
• Now add some water containing ethanol and put the switch ON.
• Repeat the experiment with glucose solution.
Observation : K The bulb will not glow and the needle of ammeter will not show deflection because glucose and ethanol do not conduct electricity.
Conclusion: The experiment shows glucose and ethanol do not ionise in aqueous solution, that is, they do not give H+ ions, therefore cannot conduct electricity. Thus, glucose and ethanol are not categorised as acids.
