    With the exception of hydration reactions (which is a specific organic-chemistry thing), 'hydration' doesn't have any exact chemical meaning other than 'adding water' to something. For instance, some salts/minerals bind water in their crystals. If they've done so, they're 'hydrated'.

    "Hydrolysis" on the other hand, refers to the splitting of water into H+ and OH-, or in organic chemistry, to a reaction splitting a type of bond.
