- Strong & weak acids
- All acids can ionise (dissociate) in solution - splitting up to produce hydrogen ions H & another ion e.g
- Strong acids (sulfuric, hydrochloric & nitric acids) ionise almost completely in water (large proportion of acid molecules dissociate to release H ions. Have low pH (0-2)
- Weak acids (ethanoic citric & carbonic acids) don't fully ionise in water (only small proportion of acid molecules dissociate to release H ions. pH around 2-6
- Ionisation of weak acids is a reversible reaction which sets up equilibrium as only few acid particles release H ions reaction lies well to the left
- Ionisation of weak acids is a reversible reaction which sets up equilibrium as only few acid particles release H ions reaction lies well to the left
- Acid strength tells you what proportion of acid molecules ionise in water
