Because the hydration reaction of sulfuric acid is highly exothermic, dilution should be performed by adding the acid to the water rather than the water to the acid, to avoid acid splashing. Because the reaction favors the rapid protonation of water, addition of acid to the water ensures that the acid is the limiting reagent.
