Identify the base in this acid-base reaction:

o

2HC2H3O2 + Mg (OH) 2 + Mg (C2H2O2) 2 + 2H2O

O HC2H302

O Mg (OH) 2

O Mg (C2H302) 2

o H₂O

DONE

Answer: Magnesium hydroxide, Mg (OH) 2

Explanation:

2HC2H3O2 (aq) + Mg (OH) 2 (aq) → Mg (C2H2O2) 2 (aq) + 2H2O (l)

Acid + base → Salt + Water.

The equation above is an example of an acid-base reaction where the acid, aqeous 2HC2H3O2 reacts completely with an appropriate amount of the base, aqueous Mg (OH) 2 to produce salt, aqueous Mg (C2H2O2) 2 and water, liquid H2O only.

This acid-base reaction is also known as neutralization reaction.
