What is a homogeneous mixture that is in one phase called?
A solution
In a liquid solution, what is the substance that gets dissolved called?
Solute
What is the term for the substance doing the dissolving in a liquid solution?
Solvent
Why do solutions tend to retain the properties of the solvent?
Because solvent particles are typically much more abundant than the solute
How can we classify a solute in relation to a solvent?
As either soluble or insoluble
What determines if a substance will dissolve in a solvent?
If it makes favorable intermolecular contacts with solvent particles
What happens to salt when it dissolves in water?
It dissociates into sodium ions and chloride ions
Why won't a nonpolar covalent compound dissolve in water?
Because it cannot make dipole-dipole interactions with polar water molecules
What does the saying "like dissolves like" refer to?
It refers to the principle that polar solvents dissolve polar solutes and nonpolar solvents dissolve nonpolar solutes
Why is salt water considered a strong electrolyte?
Because the charged ions in solution can conduct electricity
What characterizes weak electrolytes?
They only partially ionize in solution
What is the purpose of using subscripts in molecular equations?
To show the phase of each compound
What does the term "aqueous" describe in solution chemistry?
It describes ions that dissociate in solution
What happens when ions come together to form a new compound that is insoluble in a solvent?
It will crash out of solution as a precipitate
What is a molecular equation used for in solution chemistry?
To describe substances that transform in solution
What is a net ionic equation?
It summarizes the key transformation by eliminating spectator ions
What is the first step in writing a net ionic equation?
Writing the complete ionic equation
What does splitting ionic compounds into their respective ions involve?
Remembering the common charges of the ions
What do we do with substances that are present on both sides of the complete ionic equation?
We cancel them out
What is the result of the net ionic equation?
It shows the two ions that come together to form a solid precipitate
What are the types of reactions categorized in solution chemistry?
Synthesis: Two things become one
Decomposition: One thing becomes two
Single displacement: One component swaps out
Double displacement: Two components switch places

In the reaction of acetic acid in water, which species acts as the Bronsted-Lowry acid?
Acetic acid
In the reaction of acetic acid in water, which species acts as the Bronsted-Lowry base?
Water
What does a Bronsted-Lowry acid do in a reaction?
It releases a proton
What does a Bronsted-Lowry base do in a reaction?
It accepts a proton
What ion is formed when acetic acid releases a proton?
Acetate ion
What is the conjugate base formed from acetic acid?
Acetate ion
What is the hydronium ion also known as?
Oxonium ion
How is the hydronium ion formed in the reaction?
When water accepts a proton from acetic acid
What is the conjugate acid formed when water accepts a proton?
Hydronium ion
What is the relationship between a Bronsted-Lowry acid and its conjugate base?
A conjugate base is formed when a Bronsted-Lowry acid releases a proton
What is the relationship between a Bronsted-Lowry base and its conjugate acid?
A conjugate acid is formed when a Bronsted-Lowry base accepts a proton
