Strengths of Acids and Bases (Leaving Cert Chemistry): Flashcards

Degree of ionisation (ability to donate/accept protons)

Excellent proton donors; almost complete dissociation

Poor proton donors; only partially dissociate

$\text{HCl}$, $\text{HNO}_3$, $\text{H}_2\text{SO}_4$

$\text{HF}$, $\text{HCOOH}$, $\text{CH}_3\text{COOH}$

Acid dissociation constant

Strong acids

Weak acids

Base dissociation constant

$\text{NaOH}$, $\text{KOH}$, $\text{Ba(OH)}_2$

Weak

Strength = ionisation degree; concentration = amount dissolved

Both acid/base strength AND concentration
