Answer :
(1) [tex]KOH[/tex] is act as a base and [tex]H_2SO_4[/tex] act as an acid.
(2) We can not classified as a base or an acid.
Explanation :
According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions [tex](OH^-)[/tex] when dissolved in water and an acid is defined as a substance which donates hydronium ions [tex](H_3O^+)[/tex] in water.
(1) The given chemical reaction is:
[tex]2KOH(aq)+H_2SO_4(aq)\rightarrow K_2SO_4(aq)+2H_2O(l)[/tex]
In this reaction, [tex]KOH[/tex] produces [tex]OH^-[/tex] ions and [tex]H_2SO_4[/tex] produces [tex]H^+[/tex] ions.
Thus, [tex]KOH[/tex] is act as a base and [tex]H_2SO_4[/tex] act as an acid.
(2) The given chemical reaction is:
[tex]NH_3(g)+HCl(g)\rightarrow NH_4Cl(s)[/tex]
Arrhenius concept is only applicable on aqueous solution. Thus, we can not classified as a base or an acid.
