Activity 4.6 NCERT Class 10 Science, Carbon, and its Compounds

Brief procedure:

Activity 4.6 asks us to add a few pieces of sodium metal to an ethanol solution and test for the gas evolved.

Observation: 

Ethanol reacts with sodium to form sodium ethoxide. This salt is colourless and soluble in water. Hydrogen gas evolves during the process which we check by bringing a flame to the test tube.

2C2H5OH(aq) + 2Na(s) -----> 2C2H5ONa (aq)+ H2(g)

Next: litmus paper test of acetic acid and HCl. Activity 4.7.
