Dilute, aqueous sulfuric acid is generally used to promote acid catalyzed hydration because:
these conditions have excess reactant and therefore drive the reaction towards products.
these conditions have excess product and therefore drive the reaction towards products.
these conditions remove product and therefore drive the reaction towards products.
these conditions remove reactant and therefore drive the reaction towards products.
