Chapter 15 Key Terms Flashcards
Alkaloid
Organic bases found in plants. Often poisonous.
Acid Ionization Constant (Ka)
Equilibrium constant for the ionization reaction of a weak acid
Acidic solution
Solution containing an acid that creates additional H30+ ions
Amphoteric
Able to act as an acid or base
Arrhenius Acids and Bases
Arrhenius acids produce H+ ions, Arrhenius bases produce OH- ions
Autoionization
The process that allows water to act as both a base and acid for itself
Base Ionization Constant (Kb)
Equilibrium constant for the ionization reaction of a weak base
Basic Solution
A solution that contains a base that creates additional OH-
Bronsted-Lowry Acids and Bases
Bronsted-Lowry acids donate H+, while bases accept H+
Carboxylic Acid
An organic acid with the functional group -COOH
Conjugate Acid Base Pair
Two substances related to each other by the transfer of a proton
Diprotic Acid
Acid containing two ionizable protons
Hydronium Ion
H3O+ ion that is formed by a water molecule combining with an H+ ion
Ion Product Constant of Water (Kw)
Equilibrium constant for autoionization of water
Lewis Acid
Atom, ion, or molecule that accepts an electron pair
Lewis Base
Atom, ion, or molecule that is an electron pair donor
Monoprotic Acid
Acid with only one ionizable proton
Neutral
THe state of a solution where H3O+ and OH- are equal
Percent Ionization
Concentration of ionized acid over initial acid
Polyprotic acid
Acid with multiple ionizable protons
Strong Acid
Acid that completely ionizes
Strong Base
Base that completely ionizes
Triprotic Acid
Acid with 3 ionizable protons
Weak Acid
Acid that does not completely ionize
