metal salt formation


I'm trying to form nickel acetate from nickel (II) oxide and dilute acetic acid (distilled vinegar). This is what I'm thinking:

Add 10 grams (.13 mol) Ni(II)O to 400 mL 4% v/v acetic acid (.24 mol) and heat until all Ni(II)O has dissolved. Continue to heat with stirring for 1 hr. Boil off excess vinegar to precipitate Nickel Acetate.

My thinking is that as I boil off the excess water I should be pushing the reaction equilibrium
NiO + 2AcOH <=> Ni(AcO)2 + H2O
to the right (to completion?).

My inorganic chemistry is a bit rusty so I'd love to get some comments/critiques. Especially on shifting the equilibrium.
