Write an activity to know the reaction of bases with metals.

1.	Write an activity to know the reaction of bases with metals.
Answer» Aim : Reaction of bases with metals. Materials required : Test tube, delivery tube, glass through, candle, soap water, NaOH solution and Zinc granules. Procedure : (1) Place a few granules of zinc metal in a test tube and add 10 ml of sodium hydroxide solution and warm the contents of the test tube. (2) Pass the gas being evolved through the soap water. (3) Bring a burning candle near the gas filled bubble. Observation : We will notice the gas evolved burns with a pop sound indicating H₂.(Hydrogen) The reaction is written as follows. 2 NaOH + Zn → Na₂ZnO₂ + H₂↑
