Front

If the pH of a solution is 8.00, what is the concentration of [H3O+] in M?

Back

1.0 x 10^-8 M

Front

What does a pOH of 2 indicate about ammonia?

Back

Ammonia is a base.

Front

Define pH.

Back

pH is a measure of the hydrogen ion concentration in a solution, calculated as pH = -log[H+].

Front

What is the relationship between pH and pOH?

Back

pH + pOH = 14.

Front

How do you calculate the pH of a strong acid?

Back

For a strong acid, pH = -log[H+].

Front

What is the pH of pure water at 25°C?

Back

7 (neutral).

Front

What is the significance of a pH less than 7?

Back

A pH less than 7 indicates an acidic solution.
