For each statement below, indicate whether it is true or false.
1. breaking the hydrogen bond between 2 water molecules is called dissociation.
2. when water dissociates, an oxygen atom separates from the rest of the molecule.
3. the hydroxide ion has an overall charge of negative one.
4. a hydrogen ion is the same as a proton.
5. when a hydrogen ion separates from a water molecule, it usually combines with another water molecule to form a hydronium ion.
6. a hydronium ion has the formula h2o+.
7. in pure water, at 25oc, about 10% of the water molecules are dissociated at any given time.
8. in pure water, the concentration of hydrogen ions always equals the concentration of hydroxide ions.
9. in pure water, the concentration of hydrogen ions is 1 x 107 molar.
10. water dissociates into oppositely charged ions.
