Question

describe an activity to prove that all hydrogen containing compounds such as alcohol and glucose are not acids

Answer 1

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.




Above diagram shows that an acid solution can conduct electricity.

ACTIVITY :-

• Take 3 Beakers
• Name The Beakers as A , B & C
• Take HCL in beaker A , alcohol in beaker B & glucose in beaker C
• Make a electric circuit. Connect the wire with 3 beakers.
• Beaker, in which, the bulb glows, that Beaker contain acid because acids complete disassociates into water to form H+ & OH- ions which conducts electricity.
• This activity prove that the electricity passes through completely ionised liquids are acids.
