Neutralization reaction
a reaction in which an acid reacts with a base to form water and a salt
Titration
the addition of a known amount of a solution of known concentration to determine the concentration of an unknown solution
Standard solution (titrant)
solution of known concentration
end point
when an indicator changes color in a titration

Acid
a compound that gives off hydrogen ions (H+)when dissolved in water.
Base
a compound that gives off hydroxide (oh-) ions when dissolved in water.
Acidic solution
A solution that contains more hydrogen ions (H+)than hydroxide ions(OH-)
Basic Solution
A solution that contains more hydroxide ions than hydrogen ions.
Bronsted-Lowery
an acid is a hydogen ion donor
a base is a hydrogen ion accepter
[h+] [oh-]= 1.0 x 10-14
pH = -log [H+]
Poh= -log [oh-]

Neutralization reaction
a reaction in which an acid reacts with a base to form a salt (ionic compound) and water.
Titration
a method of determining the concentration of a solution by reacting a unknown volume of that solution with a solution of known concentration (the titrant)
equivalence point
point at which the moles of hydrogen ion equal the moles of hydroxide ion.
end point
point at which the indicater used in a titration changes colors
