What is the differences between hydrolysis and hydration?

[crays]

Hi, i would like to know what is the differences between hydrolysis and hydration. I tried googling for answer but it wasn't really clear for me

http://wiki.answers.com/Q/Whats_the_difference_between_hydration_and_hydrolysis

Both process produces H⁺ and OH^- ions, so what's the differences?

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.
