The other guy explained it, I just shortened it.

Answer 2

Answer: In the given acid-base reaction, the base is
`Mg(OH)_2`

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
`Mg(OH)_2`
