This is simply a partner exchange reaction...

Explanation:

#Cu(NO_3)_2(aq) + H_3C-CO_2^(-)Na^(+) stackrel(H_2O)rightleftharpoonsCu(O_2C-CH_3)_2(aq) + 2NaNO_3(aq)#

The waters after the dot in #NaO_2C-CH_3*3H_2O# are so called solvents of crystallization. The reagent we use from the bottle is the trihydrate...and this hydration often makes it easier to measure out the mass of an equivalent molar quantity of acetate ion.
