This is a bad example...

Note: The ions from the reactants do not match up with the ions present in the products. There is no driving force either. The driving forces (factor which must occur for a reaction to occur) of double replacement reactions include:

  1. The formation of water
  2. The formation of a solid precipitate
  3. The formation of a gas.

None of these requirements is met by this example because all the reactants and products are soluble in water, so no reaction occurs. Double replacement reactions require that one driving force occur in the reaction. The reactions below are examples of DR reactions

NaCl(aq) + AgN#O_3#(aq) -> #AgNO_3#(aq) + AgCl(s)
AgCl = PRECIPITATE

HCl + NaOH -> HOH + NaCl
HOH = WATER
