Answer:
Acid : [tex]Zn(OH)_3^{-}[/tex]
Conjugate base : [tex]Zn(OH)_4^{2-}[/tex]
Base: [tex]OH^-[/tex]
Explanation:
According to the Lewis concept :
- An acid is defined as a substance that accepts electron pairs .
- Base is defined as a substance which donates electron pairs.
According to the Bronsted-Lowry conjugate acid-base theory:
- An acid is defined as a substance which looses donates protons and thus forming conjugate base .
- A base is defined as a substance which accepts protons and thus forming conjugate acid.
Given reaction :
[tex]Zn(OH)_3^{-}(aq) + OH^-(aq)\rightleftharpoons Zn(OH)_4^{2-}(aq)[/tex]
[tex]Zn(OH)_3^{-}[/tex] is acting as an acid because it is accepting hydroxide ion.And after accepting hydroxide ion it forms its conjugate base that is [tex]Zn(OH)_4^{2-}[/tex]
Since,[tex]Zn(OH)_3^{-}(aq)[/tex] is acting as an acid [tex]OH^-[/tex] will obviously act as base.
