# Why is it possible to separate mixtures of liquids by boiling?

Mar 29, 2018

Because liquids have different boiling points.

#### Explanation:

Every liquid has a different boiling point; for example, water (${H}_{2} O$) has a boiling point of $212$ degrees Fahrenheit ($100$ degrees Celsius) at sea level, and household bleach (sodium hypochlorite, or $N a C l O$) has a boiling point of $214$ degrees Fahrenheit ($101$ degrees Celsius) at sea level. (Above and below sea level, they would boil at lower and higher temperatures, respectively).

If you had a water-bleach mixture (they will actually dissolve because they are both polar), and you heated it to $212$ degrees Fahrenheit ($100$ degrees Celsius) at sea level, the water would evaporate, but the bleach wouldn't, leaving you with water vapor and bleach.
