Title: ZnOHNO3
Post by: Rutherford on May 12, 2012, 06:32:15 AM

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 K_a values for aqueous transition metal ions, indicating that they're weak, while I've always though that OH^- is a strong base.
