Unit 9 Review Solutions

A solution is made by dissolving some salt in a beaker of water. The salt is referred to as the:

• solute

• solution

• filtrate

• solvent

If a salt water solution was stirred, what would happen than if it were not stirred?

• more salt could be dissolved in it

• the salt would dissolve quicker

• it would heat up more

• it would have the same effect

If a salt water solution was heated, what would happen than if it was not heated?

• more salt could be dissolved in it

• it would bubble less

• the salt would dissolve quicker

• it would have the same effect
