Uses of Alcohol:

  • Ethanol is the alcohol used in alcoholic drinks. It can be used as an industrial methylated spirit where methanol is used very little in quantity as it can be dangerous.
  • It is used as fuel to produce carbon dioxide and water by the process of fermentation. Whereas methanol burns carbon dioxide and water to facilitate combustion.
  • Alcohol is an organic compound used as a solvent that is insoluble in water.
  • It can be used to lower the level of sugar.
  • Alcohol is used as a preservative in laboratories.
