Acid, Base, pH, pOH Review

Front

What is a strong base?

Back

A strong base is a substance that completely dissociates in water to form hydroxide ions (OH-).

Front

How do you calculate pH from [OH-]?

Back

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

Front

What is the pOH of a solution with [OH-] = 2.7 x 10^-4 M?

Back

pOH = 3.57.

Front

What pOH value indicates a strong acid?

Back

A pOH value less than 7 indicates a strong acid.

Front

What is a weak acid?

Back

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

Front

Define pH.

Back

pH is a measure of the acidity or basicity of a solution, calculated as pH = -log[H+].

Front

What is the relationship between pH and pOH?

Back

pH + pOH = 14.

Front

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

Back

pH = 10.92.

Front

What does a pH of 7 indicate?

Back

A pH of 7 indicates a neutral solution.

Front

What is the formula to find [H+] from pH?

Back

[H+] = 10^(-pH).
