# What kind of salt (acidic or basic) is Zn(CH_3COO)_2 solution?

Apr 23, 2016

Basic

#### Explanation:

This solution, when in water will have the following equilibrium:

$Z n {\left(C {H}_{3} C O O\right)}_{2} + 6 {H}_{2} O \rightarrow Z n {\left({H}_{2} O\right)}_{6}^{+ 2} + 2 C {H}_{3} C O {O}^{-}$

While that aqua-ion (the complex of the metallic ion with the water) can cause a mild hydrolysis liberating protons, the main acid-base equilibrium here is the one that acetate $C {H}_{3} C O {O}^{-}$ does, you see, it's a base, which means that in aqueous solution it undergoes this equilibrium:

$C {H}_{3} C O {O}^{-} + {H}_{2} O \leftrightarrow C {H}_{3} C O O H + O {H}^{-}$
