The pH Scale and Strong Acids (OCR A-Level Chemistry A): Flashcards

Søren Sørensen

$\text{pH} = -\log[\text{H}^+(\text{aq})]$

$[\text{H}^+(\text{aq})] = 10^{-\text{pH}}$

pH < 7

pH > 7

10-fold (10×) change

Completely dissociates in water

$[\text{H}^+(\text{aq})] = [\text{HA(aq)}]$

High pH

Increases by ~0.30 units
