Prize Summary

Participating Spectator Ion
Spectator anions alter the rate and mechanism
of the reaction between a metal and an acid.
In
this experiment we demonstrate that spectator ions,
chemical species that have been generally considered
to have no involvement in simple reactions such as occur
between an acid and a metal, do, on the contrary, have
a significant impact on the reaction by modifying the
mechanism by which the reaction takes place. Our research
suggests that negative ions surrounding the metal can
both inhibit the reaction and reduce the energy barrier
that needs to be overcome when an acid particle (hydroxonium
ion) interacts with the metal.
