Introduction

Electrical conductivity of bases using simple circuit

    • Sodium Hydroxide (NaOH) is a highly reactive and caustic substance. Handle the flakes and solution with extreme care and caution

    • Gloves are compulsory while handling NaOH

    • The ends of the copper wires might be sharp and delicate, be careful while handling them.

  1. Take an open circuit
    • Take an open circuit

    • Take 1g of NaOH crytal in 50 ml water

    • Take 2 ml of above solution in a bottle cap

    • Insert free ends of the copper wire in the bottle cap

    • LED starts glowing which indicates Sodium hydroxide is a conductor
