11.4 Types of Solutions and Solubility

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.

A solution that contains all of the solute it can hold at a given temperature is

• diluted.

• saturated.

• supersaturated.

• unsaturated.

Choose the correct characteristics of solution :

• Homogenous

• Does not allow light

• Cloudy

• Uniform colour

• Do not leaves remnants when filtered

How does a solution become supersaturated?

• dissolve lots of solute in it.
• dissolve a little solute in it. 
• dissolve more solute than you should be able to. 
• dissolve a solvent in it. 

Solution where more solute can still be dissolved at the given temperature. 

• Saturated
• Unsaturated
• Supersaturated
• Homogeneous solution

Which solution is concentrated?

• 25 g of salt in 100 ml of water

• 15 g of salt in 200 ml of water

• 10 g of salt in 400 ml of water

• 5 g of salt in 400 ml of water.

What happens to the concentration of saltwater if you left it boiling on a stove without a lid?

• It becomes diluted as the water evaporates

• It becomes more concentrated as the water evaporates.

• The concentration does not change.

Aqueous solutions are best described as

• homogeneous compounds

• heterogeneous compounds

• homogeneous mixtures

• heterogeneous mixtures

Which solute is the most soluble at 10 ⁰C?

• KI
• KClO₃
• NH₄Cl
• NH₃
