Acid, Base, pH, pOH Review

Front

What is a weak acid?

Back

A weak acid is a substance that only partially dissociates in water to yield H+ ions.

Front

What happens to the pH of a solution when OH- ions are added?

Back

The pH of the solution would go up.

Front

What is the pH of a solution with a pH of 7.0?

Back

A solution with a pH of 7.0 is considered neutral.

Front

What is the definition of an acid?

Back

An acid is a substance with a pH less than 7.

Front

What is the definition of a base?

Back

A base is a substance with a pH greater than 7.

Front

How do you calculate pH from [OH-]?

Back

pH = 14 - pOH, where pOH = -log[OH-].

Front

What is the pH of a solution with [OH-] = 8.41 x 10^-4?

Back

The pH of the solution is 10.92.

Front

What is the relationship between pH and pOH?

Back

pH + pOH = 14.

Front

What is a strong acid?

Back

A strong acid is a substance that completely dissociates in water to yield H+ ions.

Front

What is a strong base?

Back

A strong base is a substance that completely dissociates in water to yield OH- ions.
