Arrhenius acids and bases must be in what phase:
Aq
Arrhenius acids must ___ in water to produce ___ as the only positive ion
Ionize, H+
Arrhenius bases must ___ in water to produce ___ as the only negative ion
Dissociate, OH-
When H+ bonds to H2O, what does it form?
Hydronium, or H3O+
T/F: Arrhenius bases can contain carbon
F: they cannot; if a base contains carbon, it is an alcohol
T/F: Dissociation needs to occur before ionization
F: ionization needs to occur first!

When water reacts with a nonmetal oxide
How are metal oxides formed?
Basic anhydride combines with water
