Acids and Bases Flashcards

Vocabulary flashcards for acids and bases unit.

Arrhenius Acid

A chemical compound that increases the concentration of hydrogen ions (H+) in an aqueous solution.

Arrhenius Base

A substance that increases the concentration of hydroxide (OH-) ions in an aqueous solution.

Bronsted-Lowry Acid

A proton donor in the form of hydrogen.

Bronsted-Lowry Base

A proton acceptor in the form of Hydrogen.

Amphoteric

A substance that can act as both an acid or a base.

Strong Acid (SA)

Completely ionizes in water, produces hydronium ions in water, has the lowest values on the pH scale, results in strong electrolyte solutions in water, 100% ionization.

Weak Acid (WA)

Only partially ionizes in water, results in weak electrolyte solutions in water, less than 100% ionization or dissociation.

Strong Base (SB)

Produces hydroxide ions in water, results in strong electrolyte solutions in water, 100% Dissociation, has the highest values on the pH scale.

Weak Base (WB)

Produces hydroxide ions in water, results in weak electrolyte solutions in water.

pH

A mathematical scale representing the concentration of H3O+ ions, ranging from 0-14; the greater the [H3O+], the lower the pH.

pOH

A mathematical scale representing the concentration of OH- ions, ranging from 0-14; the greater the [OH-], the lower the pOH.

Strength (Acids/Bases)

Based on the degree to which an acid or base forms ions in water.

Strong Acid/Base

An acid or base that ionizes or dissociates completely in an aqueous solution; a strong electrolyte.

Weak Acid

An acid that releases only a few hydrogen ions in an aqueous solution.

Weak Base

A base that releases only a few hydroxide ions in an aqueous solution.
