What is the solvent in a solution?

Back

The solvent is the substance that dissolves the solute, such as water in a sugar solution.

How does stirring affect the rate of dissolving?

Back

Stirring increases the rate of dissolving by helping to distribute the solute particles throughout the solvent.

Front

What is filtration?

Back

Filtration is a method used to separate solids from liquids by passing the mixture through a filter.

Front

What is evaporation?
