Question

Compounds such as alcohol and glucose also contain hydrogen but are not categorised as acids? Describe an activity to prove it?

Answer 1

The acids are defined as the substances which easily protonate or donates the H+ from its molecular structure on reacting with water molecule. The acids shows the property of turning the litmus paper to red. E.g. $HCl \to {H^ + } + C{l^ - }$, here the hydrochloric acid has the ability to donate H+ easily. Therefore it is classified as acid.

Complete step by step answer:
To perform the activity to prove the non-acidic nature of alcohol and glucose the required materials are:
1.Glucose solution
2.Alcohol solution
3.Bulb
4.Electrodes
5.Battery
6.Switch
7.beakers

Procedure:
Take two beakers and add glucose and alcohol in each beaker. To complete the circuit insert the electrodes in the solutions in such a way that one end is attached to the bulb and the other is attached to the battery. When the switch of the circuit is switched on, the current passes through the circuit and the observation is made that the bulb did not glow up in each case. In order to glow the bulb after the, the electrons should move from the solution in the opposite direction to the movement of positive charge.
Result: The solution of glucose and alcohol do not give up ${H^ + }$ions in their solution forms, hence they are not classified as acids.

Note: The substance or the compound are acidic in nature when they in their solution state gives or donates the ${H^ + }$ion but in this activity performed there were no ${H^ + }$ ions present in the solution indicating the non-acidic behaviour of the glucose and alcohol.
