Multiple Choice

the definition of a solution is

• solute + solution

• solvent + solution

• solute + solvent

• solution + dillution

Multiple Choice

____________ is the process whereby particles of a solvent completely surround the particles of a solute, disperse them throughout the solvent particles, and hold them in solution.

• solvation

• immisciblation

• dissolution

• saturation

Multiple Choice

A solute whose water solution conducts electricity is called a(n)

• nonconductor
• electrolyte
• nonelectrolyte
• aqueous solution

Multiple Choice

Solutions in which electric currents cannot run through are said to be

• noncolloidal
• electrolytes
• nonelectrolytes
• conductors

Multiple Choice

An example of a nonelectrolyte is

• sugar water
• salt water
• sodium chloride
• hydrogen chloride

Multiple Choice

A non-electrolyte is composed of __________in solution

• molecules

• molecules and ions

• ions

• none of the above

Multiple Choice

What does "like dissolves like" mean?

• polar solvents dissolve in polar solutes

• polar solutes dissolve in polar solvents

• non-polar solvents dissolve in polar solutes

• non-polar solutes dissolve in polar solvents

Multiple Choice

Capable of being dissolved

• Soluble
• concentration
• colloid
• molarity

Multiple Choice

Sodium chloride in water

• Soluble (miscible)

• Insoluble (immiscible)

• Partially soluble

Multiple Choice

Sodium chloride in acetone (CH₃COCH₃ - nonpolar)

• Soluble (miscible)

• Insoluble (immiscible)

• Partially soluble

Multiple Choice

How does a solution become supersaturated?

• dissolve lots of solvent 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. 

Multiple Choice

When a certain amount of solvent cannot hold any more solute it is called a ________ solution.

• Diluted
• Saturated
• Unsaturated

• Supersaturated

Multiple Choice

You are given a small beaker of solution at room temp. You add a bit of solute to the solution and it dissolves. The solution was:

• saturated

• unsaturated

• concentrated

• supersaturated

Multiple Choice

How do you know when you have a saturated solution?

• You don't see anymore material in the solution. It has dissolved.

• The material dissolves and no more will dissolve because you see it collect at the bottom.

• The solution is bubbling and cloudy.

• The solution is clear and there is nothing at the bottom.

Multiple Choice

How many grams of K₂Cr₂O₇, are soluble in 100 g of water at 95 ºC?

• 83 grams
• 75 grams
• 40 grams
• 12 grams

In a solid to liquid mixture, an increase in temperature means...

• increase in solubility
• decrease in solubility

Multiple Choice

In a gas to liquid mixture, an increase in temperature means...

• increase in solubility
• decrease in solubility
