Chapter 18 Study Guide(Acids and Bases)
The pH scale allows scientists to define the acidity of a substance on a scale of ________ .
0-14
Which model states than an acid is a substance that contains hydrogen and ionizes to produce hydrogen ions?
Arrhenius Model
A conjugate acid is produced when an acid accepts a hydrogen ion.
False
A neutral solution contains more hydroxide ions than hydrogen ions.
False
Acid solutions taste bitter and basic solutions taste sour.
False
An acid anhydride is an oxide that can combine with water to form a base.
False
An acid is an ion or molecule with a lone electron pair that can donate or share.
False
An acidic solution contains more hydroxide ions than hydrogen ions.
False
An aqueous solution of acid causes red litmus paper to turn blue.
False
An aqueous solution of acids and bases cause red litmus paper to turn blue
False
Conjugate acids and bases react to form Bronsted-Lowery acids band bases.
False
In a typical reaction, if the reacting acid is strong, the base produced is strong.
False
The Arrhenius model states that acids and bases share electron pairs.
False
A single arrow in a reaction means that the reaction goes to completion.
True
Acids add flavor to many beverages and foods.
True
Acids and bases have the ability to conduct electricity.
True
In solution, strong acids and bases ionize completely, but weak acids and bases ionize only partially.
True
Substances that can act as both an acid and a base are said to be amphoteric.
True
The relative amounts of hydrogen and hydroxide ions determine whether an aqueous solution is acidic, basic, or neutral.
True
Weak acids produce fewer ions than strong acids and cannot conduct electricity as well.
True
In the Bronsted-Lowery model of acids and bases, an ________ is a hydrogen donor and a ________ is a hydrogen acceptor.
acid, base
A ________ is produced when a base accepts a hydrogen ion from an acid.
conjugate acid
The ________ of a weak acid is strong.
conjugate base
When acids react with metals, they produce ________ gas.
hydrogen
A basic solution contains more ________ ions than hydrogen.
hydroxide
An acid that can donate only one hydrogen ion is called a ________ acid
monoprotic
A solution that contains equal concentrations of hydrogen and hydroxide ions is a ________ .
neutral solution
An acid that can donate more than on hydrogen ion is called a ________ acid.
polyprotic
