The base is under a"salt" by an acid
Just concentrate
What scale are we using
100
type of homogeneous mixture that is uniform throughout.
What is a solution
100
These are are responsible for holding molecules together
What are intermolecular forces?
100
Acids, bases, and salts are examples of this type of substance.
What is an electrolyte?
100
Concentration is measured in these units
What are moles/liters or Molarity
100
This is what is used to determine the concentration of hydrogen ion.
What is pH?
200
This component in solutions is responsible for dissolving and is typically found in excess.
