Dissolving
A qualitative way to describe a solution that has a LOT of solute dissolved in it
What is concentrated
The amount of solute that can dissolve in a given amount of solvent at a given temperature
What is solubility
The equation for molarity
What is moles / liters
0.3 M versus 3.0 M - which is more dilute?
What is 0.3 M
The dissociation equation of NaCl
NaCl (s) + H2O --> Na+ (aq) + Cl-(aq)
Conducts electricity when dissolved in water
What is an electrolyte
A solution that contains the maximum amount of dissolved solute
What is a saturated solution
The moles of NaCl present in 1 L of a 5.0 M solution
What is 5 moles
Dissociation equation of Na3PO4 (s)
Na3PO4 (s) + H2O -> 3Na+ (aq) + PO43- (aq)
This type of compound is a nonelectrolyte
What is a molecular (or covalent) compound
Causes the solubility of gases to decrease and the solubility of liquids to increase
What is an increase in temperature
The number of moles present in a 400.0 mL solution with a concentration of 0.157 M
What is 0.0628 moles
The volume of 2.0 M NaOH solution needed to make 175 mL of a 0.35 M solution
What is 31 mL
The separation of ions when an ionic compound is dissolved in water
What is dissociation

These are the steps required to dilute a 5.0 M solution and make 120 mL of a 1.8 M solution
What is
1. Measure out 43 mL of the 5.0 M solution
2. Add water to it until the total solution volume is 120 mL
