Ionization of acids and Bases
Ionisation of Acid & Base
- Strong Acid are 100% ionisable. Eg: hydrochloric acid (HCl), hydrobromic acid(HBr), hyrdoiodic acid (HI)
$H Cl -> H^+ + Cl^-$
$H Br -> H^+ + Br^-$
$H I -> H^+ + I^- $
- Weak Acid are not 100% ionisable. Eg: $CH_3 COOH$, $HNO_2$
$CH_3 COOH -> CH3 COO^- + H^+$
- Strong Base are 100% ionisable Eg: NaOH,KOH
$NaOH -> Na^+ + OH^-$
- Weak Base are Not 100%ionisable
$NH_4 OH -> NH_4^+ + OH^-$
- Ionisation of Acid & Base is a dynamic equlibrium as per Lewis Bronsted Theory
- The equilibrium moves in the direction of formation of weaker acid and weaker base because the stronger acid donates a proton to the stronger base
- strong acids have very weak conjugate bases while weak acids have very strong conjugate bases
- very strong base would give a very weak conjugate acid
