Partial Pressure & Separation Techniques (Pre-AP Chem 2.4-2.5)

Front

What is partial pressure?

Back

Partial pressure is the pressure that a gas in a mixture would exert if it occupied the entire volume by itself. It is a key concept in understanding gas mixtures.

What is mole fraction?

Back

Mole fraction is the ratio of the number of moles of a component to the total number of moles in the mixture. It is a dimensionless quantity.

What separation technique is used to separate liquids with different boiling points?

Back

Distillation is the separation technique used to separate two liquids based on their different boiling points.

Front

What is the definition of distillation?

Back

Distillation is a separation process that involves heating a liquid to create vapor and then cooling the vapor to create a liquid, effectively separating components based on boiling points.
