Unit 2 AOS 2 Review (so far...)

W6L2: When a solvent contains as much of the solute as it can hold, the solution is said to be

• supersaturated
• diluted
• saturated
• unsaturated

W6L2: 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 super amount of solvent in it. 

W6L2: What does it mean to dilute a solution?

• lower the concentration of solute per solvent
• increase the concentration of solute per solvent

W6L2: Solution where more solute can still be dissolved at the given temperature. 

• Saturated
• Unsaturated
• Supersaturated
• Homogeneous solution

W6L2: mixture of two or more substances; dissolved particles are spread evenly throughout the mixture

• solvent
• solute
• mixture
• solution

W6L2: If I dissolve carbon dioxide in water, what is my solvent?

• Carbon Dioxide
• There is no solvent
• Oxygen
• Water

W6L2: If I dissolve sugar in water, what is the solute?

• Water
• Hydrogen
• Sugar
• Carbon

W6 L1: What is the concentration (in g L^-1) of a solution containing 10.0 g of sodium chloride in 500 mL of water?

• 0.02 g L^-1

• 20.0 g L^-1

• 0.0000200 g L^-1

• 20.0 x 10^-3 g L^-1

W6L1: What units can we measure concentration in? (tick all that apply)

• mol L^-1

• ppm

• g L^-1

• percentage by volume

• percentage mass/volume

W6L1: What does ppm stand for?

• parts per million

• precipitating particle moles

• precipition per moles

• parts precipitating in moles

• None of the above
