Compounds such as alcohol and glucose also contain hydrogen but are not characterised as acids. Describe an activity to prove it.
Compounds such as alcohol and glucose also contain hydrogen but do not behave like an acid. Both are organic compounds with the formulae C2H5OH and C6H12O6, respectively.
This can be proved by the following activity:
In a glass beaker, take a dilute solution of glucose (C6H12O6). Fix two small nails of iron in a rubber cork and place the cork in the beaker as shown in the figure. Connect the nails to the terminals of a 6 volt battery through a bulb. Switch on the current. The bulb will not glow. This shows that the electric current has not passed through the glucose solution. As the current is carried by the movement of ions, it shows that the solution of
Glucose solution in water does not conduct electric current
glucose has not given any H+. Now repeat the same experiment with ethyl alcohol (C2H5OH). The bulb will again not glow. This shows that both of them do not behave as acids although they contain hydrogen atoms in their molecules.
