Science 7 - Solutions & Solubility

What is a solvent

• A liquid that will dissolve a solid solute

• Another word for solution

• A thing that make drinks change colour

• Usually the solid about to be dissolved

If I dissolve sugar in water, what is the solute?

• Water
• Hydrogen
• Sugar
• Carbon

When a solvent contains as much of the solute as it can hold, the solution is said to be

• supersaturated
• diluted
• saturated
• unsaturated

__________ are made up of solutes and solvents.

• Solutions
• Suspensions
• Heterogeneous Mixtures
• Pure Substances

Which would NOT increase the rate at which a sugar cube dissolves?

• Reducing the amount of solvent

• Crushing the sugar cube

• Stirring the solution

• Heating the solvent

You can make a solute dissolve more quickly in a solvent by

• adding more solute.

• adding ice.

• heating the solvent.

• removing some solvent.
