Using the Arrhenius concept of acids and bases, identify the Arrhenius acid and base in each of the following reactions: 2KOH(aq)+H2SO4(aq)→K2SO4(aq)+2H2O(l ) NH3(g)+HCl(g)→NH4Cl(s) Drag the appropriate items to their respective bins.

Answer :

(1) is act as a base and 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 when dissolved in water and an acid is defined as a substance which donates hydronium ions in water.

(1) The given chemical reaction is:

In this reaction, produces ions and produces ions.

Thus, is act as a base and act as an acid.

(2) The given chemical reaction is:

Arrhenius concept is only applicable on aqueous solution. Thus, we can not classified as a base or an acid.
