• 30 grams of NaCl in 100 grams of water

• 30 grams of NaCl in 200 grams of water

Based on Reference Table G, what is the maximum number of grams of KCI_(s) that will dissolve in 200 grams of water at 50°C to produce a saturated solution?

• 38g

• 42g

• 58g

• 84g

__________ are made up of solutes and solvents.

• Solutions
• Suspensions
• Heterogeneous Mixtures
• Pure Substances

What is a solute?

• The substance that does the dissolving in a solution.
• The substance that is dissolved into the solution.
• The mixing of different substances.
• The process in which neutral molecules lose or gain electrons

What does it mean to be "Soluble" ?

• Capable of being a solid.
• To have soul.
• Capable of being dissolved.
• To sink.

An unsaturated solution is one that....

• contains the maximum amount of dissolved solute.
• contains less solute than a saturated solution.
• contains more solute than a saturated solution.
• is the amount of a substance required to form a saturated solution.

A supersaturated solution is one that....

• contains the maximum amount of dissolved solute.
• contains less solute than a saturated solution.
• contains more solute than a saturated solution.
• is the amount of a substance required to form a saturated solution.
