Learn about solutions, solubility, and how to separate the components of a mixture.
A solution forms when a solute (the substance being dissolved) mixes evenly into a solvent (the substance doing the dissolving).
In salt water, what is the solute and what is the solvent?
Salt is the solute; water is the solvent
Why is water often called a 'universal solvent'?
Because it can dissolve a very wide range of substances, more than most other liquids
Solubility describes how much of a solute can dissolve in a solvent at a given temperature. Concentration describes how much solute is present in a given amount of solution.
Why does sugar dissolve faster in hot water than in cold water?
Higher temperature gives particles more energy, helping the sugar dissolve more quickly and in greater amounts
If you keep adding salt to water until no more will dissolve, what have you created?
A saturated solution
