Question

What happens when a cold and concentrated solution of sodium chloride reacts with ammonia and carbon dioxide? Write the equation of the reaction that takes place.

Answer 1

It is found that when a cold and concentrated solution of sodium chloride reacts with ammonia and carbon dioxide there is a formation of a white crystalline solid, which is slightly alkaline and salty in nature.

Complete answer:
- It is found that when a cold and concentrated solution of sodium chloride reacts with carbon dioxide and ammonia, there is formation of ammonium chloride and sodium hydrogen carbonate takes place.
- We can write the equation of the reaction that takes place as:
$NaCl+N{{H}_{3}}+{{H}_{2}}O+C{{O}_{2}}\to NaHC{{O}_{3}}+N{{H}_{4}}Cl$
- We know that Sodium hydrogen carbonate $NaHC{{O}_{3}}$, is also called sodium bicarbonate or baking soda. Basically it is a salt which is composed of a sodium cation $(N{{a}^{+}})$ and a bicarbonate anion $(HC{{O}_{3}}^{-})$. It is found to be economically important as it is used in baking and also acts as a leavening agent.

Hence, we can conclude that when a cold and concentrated solution of sodium chloride reacts with ammonia and carbon dioxide there is formation of ammonium chloride and sodium hydrogen carbonate takes place.

Note: - We should not get confused in baking soda and baking powder. Baking soda is found to have only one ingredient that is Sodium Bicarbonate. It is found to react immediately with acids.
- Whereas, baking powder consists of many ingredients like bicarbonates (typically baking soda), and acid salts. It does not immediately react with acids.
