1.

Compounds such as alcohols and glucose also contain hydrogen but arenot categorised as acids. Describe an Activity to prove it.

Answer»

Solution :Two nails are fittedon a cork and are kept in a 100 ML beaker , The nailsare then connected to the two terminals of a 6 voltbattery through a bulb and a switch , Some dilute HCl is poured in the beaker and the current is switch on . The same experiment is then performed with glucose solutions and alcohol solutions.

Obeservation :- It will be observed that the bulb glows in the HCl solutions and does not GLOW in the glucose solutions .
Result :- HCl DISSOCIATES into `H^(+) `and `Cl^(-) `ions . These ions CONDUCT ELECTRICITY in the solutions resulting in the glowing of the bulb . on the other hand the glucose solutions does not dissociate into ions . Therefore it does not conduct electricity .
Conclusion:- Fromthis activity it canbe concluded that all acids contains hydrogen ions .That is why though alcohols and glucose contains hydrogen , they are not categoresed as acids.
