Single Replacements
What is an anion?
A negative ion.
What is a cation?
A positive ion.
What do Ionic equations show?
All the ions (charges) of the reaction.
What is the formula for Molarity?
Moles of solute/ liters of solution
What is Solubility?
The ability of a substance to dissolve.
What is the "formula" for single replacement reactions?
A + CB = AB + C
What is the "formula" for double displacement reactions?
AB + CD = AD + CB
What do Net Ionic Reactions Show?
The reaction that actually occurs along with its ions.
What kinds of units must you use in Molarity equations?
Moles and Liters.
What is a Solute and Solvent?
The substance being dissolved - Solute
The substance doing the dissolving - Solvent
How do you read the solubility chart?
Teacher approval.
What kind of ions exchange in double and single replacements?
Cations (positive ions)
What are spectator ions?
Ions that do not react in a replacement reaction.
What is Molarity?
A measure of concentration of particles in a solution.
What is an electrolyte?
Ions that produce electricity.
Balance the reaction:
Li + Cu(NO3)2 ->
Cu + 2LiNO3
Balance the reaction:
Ba(NO3)2 + MgSO4 ->
Mg(NO3)2(aq) + BaSO4(s)
What must you show in Ionic equations?
+ ions, - ions, and states of matter.
How do you find moles?
How you convert milliliters into liters?
moles = grams/molar mass
mL -> L = divide milliliters by 1000
What is an aqueous solution?
A solution that has a solute dissolved in a solvent.
What are the rules for single displacement reactions?
Look at the compound and determine if it is aqueous.
If it is aqueous you run the reaction no matter what.
If it is solid, liquid, or gas you check your solubility chart to determine if a reaction will happen.

What are ALL the rules for Double Displacement reactions?
Teacher approval.
Write the net ionic equation for the following replacement reaction:
Ba(NO3)2 + MgSO4
Ba+2 + SO4-2 => BaSO4
What is the Molarity of a solution containing 45.3 grams of KNO3 and 375 milliliters of water?
1.195 Molarity
