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.


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.
