Question:
Does the reaction rate and temperature of vinegar change when magnesiun ribbon is added?


Replies:
Aaron,

Vinegar alone undergoes no reaction or temperature change -- other than the temperature it has sitting in the bottle. However, if you pour some on a piece of magnesium ribbon a reaction will occur and the temperature of the liquid will rise. The reaction is:
Mg + 2 HC2H3O2  ====>  Mg(C2H3O2)2 + H2 + Heat

Regards
ProfHoff
