Brownsted-lowry theory

• proton donor 


  any substance with H can be an acid

  contains H+ ion
• proton acceptor 


  in order to accept a proton a base has to contain a lone pair of electrons

  forms a dative bond with proton
• conjugate acid-base pair 


  consists of 2 substances that differ only by a presence of a proton (H+)
• types of acids

  can donate 1 proton - monoprotic

  can donate 2 protons - diprotic
• types of bases 


  can accept 1 proton - monoprotic base

  can accept 2 protons - diprotic / diacidic base
• amphoteric substance 


  substance that can act as a base or acid
• strong acid 


  completely disassociated in aqueous solution
• weak acid

  only partially disassociates in aqueous solution
• pH and concentration of H+ ions 


  the H+ ion concentration is related directly to the concentration of the acid
