Question

Write a net ionic equation for the reaction of hydrochloric acid with ammonia in aqueous solution. And write a net ionic equation for the reaction Sodium hydroxide (aq) + ammonium chloride (aq).

Answer 1

Explanation:

(a)  When aqueous solution of hydrochloric and ammonia chemically react together then it results in the formation of ammonium chloride.

The reaction equation for this reaction is as follows.

          $HCl(aq) + NH_{3}(aq) \rightarrow NH_{4}Cl(aq)$

Now, ioni equation for this reaction is as follows.

     $H^{+}(aq) + Cl^{-}(aq) + NH_{3}(aq) \rightarrow NH_{4}^{+}(aq) + Cl^{-}(aq)$

Cancelling the spectator ions, the net ionic reaction equation is as follows.

       $H^{+}(aq) + NH_{3}(aq) \rightarrow NH^{+}_{4}(aq)$    

(b)   When sodium hydroxide chemically reacts with ammonium chloride then it forms ammonia, water and sodium chloride as follows.

     $NaOH(aq) + NH_{4}Cl(aq) \rightarrow NH_{3}(aq) + NaCl(aq) + H_{2}O(l)$

Now, the total ionic equation will be as follows.

  $Na^{+}(aq) + OH^{-}(aq) + NH^{+}_{4}(aq) + Cl^{-}(aq) \rightarrow NH_{3}(aq) + Na^{+}(aq) + Cl^{-}(aq) + H_{2}O(l)$

Cancelling the spectator ions from the above equation. Then the net ionic equation will be as follows.

        $OH^{-}(aq) + NH^{+}_{4}(aq) \rightarrow NH_{3}(aq) + H_{2}O(l)$  

Answer 2

Answer:

(a)  When aqueous solution of hydrochloric and ammonia chemically react together then it results in the formation of ammonium chloride.

The reaction equation for this reaction is as follows.

         

Now, ioni equation for this reaction is as follows.

    

Cancelling the spectator ions, the net ionic reaction equation is as follows.

          

(b)   When sodium hydroxide chemically reacts with ammonium chloride then it forms ammonia, water and sodium chloride as follows.

    

Now, the total ionic equation will be as follows.

 

Cancelling the spectator ions from the above equation. Then the net ionic equation will be as follows.
