Compounds such as alcohols and glucose contain hydrogen but are not categorized as acids. Describe an activity to prove it

Explanation

1) Prepare solutions of glucose, alcohol, hydrochloric acid and sulphuric acid, etc.
2) Connect two different coloured electrical wires to graphite rods separately in a 100 ml beaker as shown in figure.
3) Connect free ends of the wire to 230 V AC plug and complete the circuit, by connecting a bulb to one of the wires.
4) Now pour some dilute HCl in the beaker and switch on the current.
5) We observe that the bulb glows.
6) Repeat the activity with dilute sulphuric acid glucose and alcohol.
7) We observe that the bulb glows only in sulphuric acid solution, but not in glucose and alcohol solutions.
8) Glowing of bulb indicates that there 'is flow of electric current through the solution.
9) Acid solutions have ions and the moment of these ions in solution helps for flow of electric current through the solution.
10) The positive ion present in HCl solution is H+. This suggests that acids produce hydrogen ions (`H^+`) in solution, which are responsible for their acidic properties.
11 ) In glucose and alcohol solution, the bulb did not glow indicating the absence of `H^+` ions. they contain hydrogen.
12) Hence glucose and alcohol are not categorized as acids.
