Solutions Review

Front

What is solubility?

Back

The extent to which a solute may be dissolved in water, or any solvent.

Front

True or False: The moles of solute can be determined by multiplying the molarity of the solute by the volume of solvent.

Back

True

Front

What characterizes a saturated solution?

Back

A saturated solution is one that contains the maximum amount of dissolved solute.

Front

Calculate the molarity: What is the molarity of a 2 liter solution containing 5 moles of NaCl?

Back

2.5 moles/liter

Front

How many moles of NaCl are present in 6000 mL of a 1.5 M NaCl solution?

Back

9 moles NaCl

Front

What is a buffer solution?

Back

A buffer solution is a solution that resists changes in pH when small amounts of acid or base are added.

Front

Define aqueous solution.

Back

An aqueous solution is a solution in which water is the solvent.

Front

What does miscible mean?

Back

Miscible refers to the ability of two substances to mix in all proportions, forming a homogeneous solution.

Front

What is the formula for calculating molarity?

Back

Molarity (M) = moles of solute / liters of solution.

Front

What is the difference between a saturated and an unsaturated solution?

Back

A saturated solution contains the maximum amount of dissolved solute, while an unsaturated solution contains less solute than it can hold.
