Front

What does it mean to dissolve a substance in a liquid?

Back

To dissolve means to mix evenly into a liquid by breaking into pieces that are too small to see.

Oil and vinegar need an emulsifier to mix properly.

Front

How does stirring a solution affect its solubility?

Back

Stirring a solution increases its solubility by helping the solute to disperse more evenly.
