Isopropyl Alcohol: Pure Substance or Mixture?

Isopropyl alcohol, also known as isopropanol, is a common household chemical and is widely used as a solvent and disinfectant. It is classified as a pure substance and not a mixture. Isopropyl alcohol is a clear, colorless liquid with a characteristic odor. It is a simple compound with the chemical formula C3H8O and is composed of carbon, hydrogen, and oxygen atoms.

Isopropyl alcohol is commonly available in different concentrations, such as 70% and 99%, but regardless of the concentration, it is still considered a pure substance. The different concentrations simply indicate the amount of isopropyl alcohol present in a given volume of the solution. For example, a 70% isopropyl alcohol solution contains 70% isopropyl alcohol and 30% water.

Isopropyl alcohol is flammable and should be handled with care. It has a wide range of applications, including as a solvent for coatings, inks, and adhesives, as well as a cleaning agent and disinfectant in healthcare settings and households.
