strong & weak acids

• | acids makes PROTONS in water

  • acids IONISE in aqueous solutions
  • they produce H+ IONS
  • HCl -> H+ + CL-
  • these acods dont produce hydrogen until in water
  • H+ ion is a proton
• | acids can be strong or weak

  • STRONG acids IONISE completely in water
  • all acid particles DISSOCIATE to release H+ ions
  • WEAK acids DONT fully ionise in solution
  • only a small proportion dissociate to release H+ ions
• | strong & weak acids

  • ionisation of weak acids is REVERSIBLE which sets an equilibrium between the dissociated & undissociated acid
  • position of equilibrium lies to the LEFT as only a few H+ are released
