Front
What is pOH?
Back
pOH is a measure of the hydroxide ion concentration in a solution, defined as pOH = -log[OH⁻]. It indicates how basic a solution is.
3.
FLASHCARD QUESTION
Front
What is the relationship between pH and pOH?
Back
pH + pOH = 14 at 25°C. This relationship shows that as the acidity of a solution increases (lower pH), the basicity decreases (higher pOH), and vice versa.

FLASHCARD QUESTION
Front
How do you calculate the [H⁺] from pH?
Back
To find the hydrogen ion concentration from pH, use the formula [H⁺] = 10^(-pH).
