Term
Neutralization reaction
Definition
When an Arrhenius acid and base react in a solution to produce a salt and water
Term
Titration
Definition
a controlled neutralization reaction using an acid or base of known concentration (the standard solution) to determine the concentration of another soultion, usin gan indication to determine the end point
Term
Standard Solution
Definition
the acid or base on known concentration in a titration
Term
End Point
Definition
in a titration, the point at which the indicator changes color. Normally used to determine when the neutralization is complete.
Term
Titration Equation
Definition
Ma*Va=Mb*Vb

M=molarity
V=Volume
Term
Hydrolysis
Definition
When the cations or anions of a dissociated salt remove hydrogen ions from, or donate them to a solution
Term
Buffers
Definition
Solutions that contain weak acids or bases that resist changes in pH
Term
Strong Acid
Definition
substances that completly ionize in aqueous solutions
Term
Weak Acid
Definition
ionize only slightly in an aqueous solution
Term
Strong Base
Definition
Virtually 100% dissociation
Term
Weak Base
Definition
tend to Brownstead Lowry Bases and produce smaller concentration of OH
Term
Dissociation Energy
Definition
The total energy required to break the bond between two covelently bonded atoms
Term
Free Energy
Definition
The energy from a chemical or physical process that is available to do work. Spontaneous reactions produce free energy
Term
Spontaneous reactions
Definition
Reactions that occur naturally and favor the formation of products Kep ? 1
Term
NonSpontaneous reactions
Definition
reactions that do not naturally favor the fomation of products Keq ?1
Term
Entropy (S)
Definition
the measure of how disordered or random a system is
Term
Factors affecting Entropy
Definition
1. Entropy of a substance increases as you go from solid to liquid to gas
2.Entropy increases when a substanfce is divided into parts
3. Entropy increases in a process in which the toatal number of product particles is greater than the total number of reactant particles
4.Entropy increases when the temperature increases
