Acids and Bases Flashcards
Amphiprotic
Substance that can behave as an acid or a base
Arrhenius Theory
Acid: Dissociates to produce H+
Base: Dissociates to produce OH-
Autoionization
Water reacting with itself to produce a positive and negative ion
Bronsted-Lowry Theory
Acid: Proton Donor
Base: Proton Acceptor
Buffer Capacity
A solution’s ability to resist large changes in pH when acid/base is added
Buffer Solution
Contains a weak acid/base and it’s conjugate that is resistant to large changes in pH
Corrosion
Oxidation of a metal
Hydronium Ion
Water molecule with a positively charged hydrogen ion
H30+
Ion Product for Water
Equation for hydronium and hydroxide ion concentration
1.0 x 10^-14
Monoprotic Acid
Acid that can only donate one proton to an aqueous solution
Oxidation
A loss of electrons in organic compounds
Loss of hydrogen OR gain of oxygen
Oxidizing agent
Substance that removes electrons from another substance
Gains Electrons
pH Scale
Measure of hydrogen ion concentration
0-14
Polyprotic Acid
Acid that can donate more than one proton
Reducing Agent
A substance that donates electrons to another substance
Loses Electrons
Reduction
Gain of electron in organic compounds
Gain of hydrogen OR loss of oxygen
Strong Acid
Acid that completely ionizes
Gives off the greatest number of hydrogen ions or protons
Strong Base
Base that completely ionizes
Weak Acid/Base
Partial Ionization
What are the strong acids?
Hydrochloric Acid
Nitric Acid
Sulfuric Acid
What are the strong bases?
Sodium hydroxide
Potassium hydroxide
What are the weak acids?
Acetic Acid
Carbonic Acid
What are the weak bases?
Pyridine
Aniline
Methylamine
Conjugate Acid
Formed when a base accepts a proton
Conjugate Base
Formed when an acid donates a proton
What is an electrolyte?
Aqueous solution of an acid and a base
Nuetralization
Acid and base reaction producing salt and water
Titration
Addition of a known concentration to neutralize the second unknown solution
Where does pH play a major role in our lives?
Agriculture, Physiology, Acid rain, Drug delivery
Buffer Action
Equilibrium between Weak acid/base and conjugate base/acid
LeChatelier’s Principle
A system when stressed will shift it’s equilibrium to relieve stress
Bleaching Agents
Most often oxidizing agents
Not colored; stain removers
