Sucrose + Water ---> ???

hi everyone,,
im struggling in the part where you hav to find the equation above.
can somebody help me??
thank you...

and plus if anyone knows how the ionization reaction (of sucrose and water) occurs could u please post that too. Thank you very much.

sdekivit:
in the presence of an acid we get:

sucrose + H2O --> glucose + fructose

sucrose is a disaccharide that contains an alfa-D-glucose linked to an beta-D-fructose via an acetalbonding. in the presence of an acid, the sucrosemolecule splits, where glucose gains the O of the acetal bonding and the H(+) from water. Fructose gains the OH(-) from water.

Are you interested in dissolution, or in hydrolysis?

If in hydrolysis - see sdekivit answer.

If in dissolution - sucrose 'just' dissolves, it doesn't dissociate (as your ionization remark suggests).
