An example of an ion exchange reaction is the reaction between sodium chloride (NaCl) and silver nitrate (AgNO3) to form sodium nitrate (NaNO3) and silver chloride (AgCl). The large excess of alcohol is used to drive the reaction forward. This is generally done via the introduction of an acid or base catalyst to the reaction mixture. Ester interchange rates were sensitive to the size of both the transferring OR A chemical reaction (esterification) within a molecular monolayer at the liquid-solid interface without any catalyst was studied using ambient scanning tunneling microscopy.
