As shown in figure insert two nails on the wooden or rubber cork and place it in a beaker. Now connect these iron nails with a bulb, a 6 volt battery and a switch using a wire. Now pour some alcohol or glucose such that the nails will dip into it. Now turn the switch on, you will see that the bulb will not glow. Now empty the beaker and add some HCl aqueous solution at this time the bulb will glow. This proves that an acid can conduct electricity while alcohols and glucose cannot, even when they are containing hydrogen.

prepare solutions of glucose,alcohol,hydro caloric acid and sulphuric acid
connect two different coloured wires to graphite rods separately in a 100 ml beaker
Connect free ends of the wire to 230volts AC plug and complete the circuit by connecting a bulb to one of the wires now pour some dil. hcl in the beaker and switch on the current
you will notice that the bulb glows only in acid solutions but not in glucose and alcohol solutions glowing of bulb indicates that there is flow of current through the solution acid solutions have ions and the movement of these ions help for flow of electric current through the solution the positive ion present In HCL this suggests that acids produce hydrogen ions in solution which are responsible for there acidic properties. in glucose and alcohol solution bulb did not glow indicating absence of hydrogen ions in these solutions. the acidity of acids is attributed to the hydrogen ions produced by them in solutions.
