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.

Hydrolysis and hydration are two different chemical processes that involve the addition of water molecules to a substance. The main difference between these two processes lies in their specific mechanisms and the types of substances involved.

Hydrolysis is a chemical reaction that breaks down molecules into smaller components by using water molecules. This process involves the breaking of chemical bonds between the molecules and the water molecules. In this reaction, a water molecule is split into H+ and OH- ions, which are then used to break the bonds in the molecule. This results in the formation of two or more new molecules.

On the other hand, hydration is a physical process that involves the addition of water molecules to a substance without breaking any chemical bonds. This process occurs when water molecules surround and interact with a substance, forming a solution. Unlike hydrolysis, hydration does not result in the formation of new molecules.

Another difference between hydrolysis and hydration is the types of substances involved. Hydrolysis typically occurs in the presence of a catalyst, such as an enzyme, and involves the breakdown of larger molecules, such as proteins, carbohydrates, and lipids. Hydration, on the other hand, can occur in both organic and inorganic substances, and does not require a catalyst.

In summary, the main differences between hydrolysis and hydration are their mechanisms, the types of substances involved, and the end products. Hydrolysis involves the breaking of chemical bonds and the formation of new molecules, while hydration is a physical process that does not result in the formation of new molecules. Both processes are important in various biological and chemical reactions and play crucial roles in maintaining the balance of substances in living organisms.
