AP CHEM UNIT 8.1-3 Flashcard

Front

What is the pOH of a solution if [OH-] = 2.7 x 10^-4 mol/L?

Back

3.56

Front

What do the pH and pOH of a solution add up to?

Back

14

Front

If the pH of a solution is 5.6, what is the pOH?

Back

8.4

Front

What type of solution has equal concentrations of H3O+ and OH- ions?

Back

Neutral solution

Front

What is the hydronium ion concentration if the pH is 8.43?

Back

3.7 x 10^-9 M

Front

Define pH.

Back

pH is the negative logarithm of the hydronium ion concentration, pH = -log[H3O+].

Front

Define pOH.

Back

pOH is the negative logarithm of the hydroxide ion concentration, pOH = -log[OH-].

Front

What is the relationship between pH and pOH?

Back

pH + pOH = 14.

Front

What is the pH of a neutral solution at 25°C?

Back

7.0

Front

How do you calculate the concentration of H3O+ from pH?

Back

[H3O+] = 10^-pH.
