Answer :
(1) [tex]H_2O[/tex] is a Lewis-base and [tex]Fe(NO_3)_3[/tex] is a Lewis-acid.
(2) [tex]NH_3[/tex] is a Lewis-base and [tex]HCl[/tex] is a Lewis-acid.
Explanation :
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
(1) The given balanced chemical reaction is:
[tex]Fe(NO_3)_3(s)+6H_2O(l)\rightarrow [Fe(H_2O)_6]^{3+}(aq)+3NO_3^-(aq)[/tex]
In this reaction, [tex]H_2O[/tex] is an electron pair donor and [tex]Fe(NO_3)_3[/tex] is an electron pair acceptor.
Thus, [tex]H_2O[/tex] is a Lewis-base and [tex]Fe(NO_3)_3[/tex] is a Lewis-acid.
(2) The given balanced chemical reaction is:
[tex]NH_3(g)+HCl(g)\rightarrow NH_4Cl(s)[/tex]
In this reaction, [tex]NH_3[/tex] is an electron pair donor and [tex]HCl[/tex] is an electron pair acceptor.
Thus, [tex]NH_3[/tex] is a Lewis-base and [tex]HCl[/tex] is a Lewis-acid.
The following data is observed:
(1) H₂O is a Lewis-base and Fe(NO₃) is a Lewis-acid.
(2) NH₃ is a Lewis-base and HCl is a Lewis-acid.
Lewis concept:
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
(1) The given balanced chemical reaction is:
[tex]Fe(NO_3)_3(s)+6H_2O(l)----- > Fe(H_2O)^{3+}(aq)+3NO_3^-(aq)[/tex]
Thus, H₂O is a Lewis-base and Fe(NO₃) is a Lewis-acid.
(2) The given balanced chemical reaction is:
[tex]NH_3(g)+HCl(g)----- > NH_4Cl(s)[/tex]
Thus, NH₃ is a Lewis-base and HCl is a Lewis-acid.
