Answer: In the given acid-base reaction, the base is

Step-by-step explanation:

Acids are defined as the chemical species which donate hydrogen ions when dissolved in water.

$HA(aq.)\rightarrow H^+(aq.)+A^-(aq.)$

Bases are defined as the chemical species which donate hydroxide ions when dissolved in water.

$BOH(aq.)\rightarrow B^+(aq.)+OH^-(aq.)$

The given chemical equation follows:

$2HC_2H_3O_2+Mg(OH)_2\rightarrow Mg(C_2H_3O_2)_2+2H_2O$

Here, magnesium hydroxide is acting as base because it dissociates into magnesium ions and hydroxide ions when dissolved in water.

The chemical equation for the ionization of magnesium hydroxide follows:

$Mg(OH)_2\rightarrow Mg^(2+)+2OH^-$

Hence, in the given acid-base reaction, the base is
