Answer:
After adding the water in the a beaker when we add the sugar, it makes a sugar syrup. After that we will add some yeast in it and keep it for 3-4 hours.
the process that will occur in this time is called as the fermentation. Fermentation produces the alcohol and we can smell the pungent smell of the ethanol.
this is the process that is used to form the alcohol for the drinking purpose as well which is a pure base.
