Well of course there is the ionization reaction....

Explanation:

#H_3C-CO_2^(-)Na^(+)(s)stackrel(H_2O)rarrH_3C-CO_2^(-) + Na^(+)#

But possibly you mean the acid-base reaction that acetate ion, as the conjugate base of a weak acid, undergoes...

#H_3C-CO_2^(-) + H_2O(l) rightleftharpoons H_3C-CO_2H + HO^-#

...and the extent of this equilibrium could be very easily quantified...of course this is an association reaction....

Sodium acetate would dissociate in water to give #Na^+# and #CH_3COO^-# ions which would slightly associate in water to give a little #OH^-#.

#CH_3COO^(-)(aq) + H_2O(l) rarr CH_3COOH(aq) + OH^(-)(aq)#

Explanation:

Water is a polar molecule because Oxygen has a higher electronegativity than Hydrogen. As a result, Oxygen has a #delta^-# charge and Hydrogen has a #delta^+# charge.

Water consists of #H^+# and #OH^-# ions.

Sodium acetate is an ionic compound formed from #Na^+# and #CH_3COO^-# ions, which dissociates in water due to its polarity.
