anonymous · Answer

A) you will find
- H2O, I guess, this is self-explainatory
- H3O+ and OH- because of water autoprotolysis
- Na+ and Cl- ions, the components of your salt (supposing that all substances are extremely pure, of course =) )
- glucose

B) hydrogen bonds will be built between the water molecules and between water and glucose. NOT between water and Na+, because these just build an electromagnetic field where the water molecule can arrange themselves. there are weak H-bond interactions between water and Cl-, I think, but these are not worth mentioning, as Cl- is also dissolved like Na+.
