Acid/Base Models
The model that must be in an aqueous solution.
What is the Arrhenius model?
1-14
What is the range of the pH scale?
Sensitive substances that show the acidity or alkalinity of a solution.
What is an indicator?
Substances that neutralize either an acid or a base.
What are buffers?
The fact that water can react with itself to form a small amount of hydronium and hydroxide ions.
What is self-ionization.
This model was created by two men and discuss the release or acceptance of protons.
What is the Bronsted-Lowry model?
The pH of a substance with a pOH of 11.7
What is 2.3 pH?
Acids that do not dissociate completely.
What are weak acids?
Water and salt.
What is commonly produced in a neutralization reaction?
1 X 10-14
What is the ionization constant of water?
This model uses electron configuration to better understand the definition of an acid or a base.
What is the Lewis model?
The pH value of a solution that is considered acidic.
What is 7 or lower?
Acids that can donate more than one proton in solution.
What are polyprotic acids?
The point in a titration where the [H3O+] and the [OH-] are equal.
What is the equivalence point.
The ionization constant of either hydronium ions or hydroxide ions.
What is 1 X 10-7
This model introduced conjugate pairs for acids and bases.
What is the Bronsted-Lowry model.
The pH of a substance with a [H3O+] of 2.0 X 10-5.
What is 4.7?
Substances that are sensitive to pH.
What are indicators?
Controlled neutralization reactions that are used to determine the unknown concentration of a solution.
What is titration?
The negative logarithm of the molar hydronium ion concentration.
What is the pH of a solution?
The model with the broadest definition and includes the most types of acids and bases.
What is the Lewis model?
The basis for the pH scale.
What is the ionization constant of water?
Solutions that may act as an acid or a base.
What are amphoteric substances?
The salt produced from
2HC2H3O2 (aq) + Ba(OH)2 (aq) --> Ba(C2H3O2)2 (aq) + 2H2O (l)
What is barium acetate?
Ba(C2H3O2)2
-log[6.2 X 10-3]
What is pH 2.2?
