Acids and Bases

Front

What is a strong base?

Back

A strong base is a base that ionizes completely in water, producing a high concentration of hydroxide ions (OH-). Example: Sodium hydroxide (NaOH).

Front

What is the pH range of acids?

Back

Acids have a pH below 7.

Front

Is NaOH the strongest base?

Back

True, NaOH is considered one of the strongest bases.

Front

What is a basic anhydride?

Back

A basic anhydride is a compound that reacts with water to form a base. Example: Aluminum oxide (Al2O3).

Front

What is a strong acid?

Back

A strong acid is an acid that ionizes completely in an aqueous solution, producing a high concentration of hydrogen ions (H+). Example: Hydrochloric acid (HCl).

What is the pH range of bases?

Back

Bases have a pH above 7.

Front

What is the difference between a strong acid and a weak acid?

Back

A strong acid ionizes completely in solution, while a weak acid only partially ionizes.

Front

What is the role of hydroxide ions in a base?

Back

Hydroxide ions (OH-) are responsible for the basic properties of a substance, making it capable of neutralizing acids.
