Explanation:

As per Brønsted-Lowry concept of acids and bases, chemical species which donate proton are called Brønsted-Lowry acids.

The chemical species which accept proton are called Brønsted-Lowry base.

(a) [tex]HNO_3 + H_2O \rightarrow H_3O^+ + NO_3^-[/tex]

[tex]HNO_3[/tex] is Bronsted lowry acid and [tex]NO_3^-[/tex] is its conjugate base.

[tex]H_2O[/tex] is Bronsted lowry base and [tex]H_3O^+[/tex] is its conjugate acid.

(b)

[tex]CN^- + H_2O \rightarrow HCN + OH^-[/tex]

[tex]CN^-[/tex] is Bronsted lowry base and HCN is its conjugate acid.

[tex]H_2O[/tex] is Bronsted lowry acid and [tex]OH^-[/tex] is its conjugate base.

(c)

[tex]H_2SO_4 + Cl^- \rightarrow HCl + HSO_4^-[/tex]

[tex]H_2SO_4[/tex] is Bronsted lowry acid and [tex]HSO_4^-[/tex] is its conjugate base.

Cl^- is Bronsted lowry base and HCl is its conjugate acid.

(d)

[tex]HSO_4^-+OH^- \rightarrow SO_4^{2-}+H_2O[/tex]

[tex]HSO_4^-[/tex] is Bronsted lowry acid and [tex]SO_4^{2-}[/tex] is its conjugate base.

OH^- is Bronsted lowry base and [tex]H_2O[/tex] is its conjugate acid.

(e)

[tex]O_{2-}+H_2O \rightarrow 2OH^-[/tex]

[tex]O_{2-}[/tex] is Bronsted lowry base and OH- is its conjugate acid.

[tex]H_2O[/tex] is Bronsted lowry acid and OH- is its conjugate base.
