Acids and Bases

Front

What are acids?

Back

Substances that donate protons (H+) in a chemical reaction.

Front

What are bases?

Back

Substances that accept protons (H+) or donate hydroxide ions (OH-) in a chemical reaction.

Front

What is the pH scale?

Back

A logarithmic scale used to measure the acidity or basicity of a solution, ranging from 0 (acidic) to 14 (basic).

Front

What is the relationship between pH and [H+] concentration?

Back

pH = -log[H+]. A lower pH indicates a higher concentration of hydrogen ions.

Front

What is a neutral solution?

Back

A solution with a pH of 7, where [H+] = [OH-].

Front

What is a strong acid?

Back

An acid that completely dissociates in water, releasing all of its hydrogen ions.

Front

What is a weak acid?

Back

An acid that partially dissociates in water, establishing an equilibrium between the undissociated acid and its ions.

Front

What is a strong base?

Back

A base that completely dissociates in water, releasing all of its hydroxide ions.

Front

What is a weak base?

Back

A base that partially dissociates in water, establishing an equilibrium between the undissociated base and its ions.

Front

What is titration?

Back

A technique used to determine the concentration of an unknown solution by adding a solution of known concentration until the reaction reaches completion.
