How does ZnOHNO3 react in a solution (acid, neutral or basic)?
ZnOHNO3 :rarrow: Zn2++OH-+NO3-
-Zn2+ will make [Zn(H2O)6]2+ that reacts like an acid:
[Zn(H2O)6]2++H2O :rarrow: [Zn(H2O)5OH]-+H3O+
-OH- reacts with H3O+ so it is basic.
Is [Zn(H2O)6]2+ a stronger acid that OH- is a base?

I think your reasoning is correct. I would expect that it would be overall basic, just going off the fact that I've seen Ka values for aqueous transition metal ions, indicating that they're weak, while I've always though that OH- is a strong base.
