Subject: What would happen if you electrolyse water in AC?

I understand this is a recipe for electrocution, however, what reactions would 
take place at each electrode? As the electrons are on 'wiggling' back an forth 
in AC does this mean that the water is unable to 'grab' electrons at the 
cathode? Could you please give some depth what is happening in electrode in 
relation to electron movement and what the water does. DC makes sense as the 
electrons are being delivered to the cathode however in AC are the electron 
movements great enough for wateer to take. kind regards Chris
