Question

Ammonium chloride with sodium hydroxide in presence of formaldehyde

Answer 1

Reaction between Ammonium Chloride and Sodium Hydroxide:

Ammonium Chloride is also known as the salt of Ammonia. It is represented by a chemical formula NH4Cl. Ammonium Chloride in its aqueous solution is acidic. Sodium Hydroxide is well known for being a strongest base. Reaction between Ammonium Chloride and Sodium Hydroxide produces some new compounds like Ammonia, Water and Sodium Chloride.

NH4Cl + NaOH `->`  NH3 + NaCl + H2O

In this reaction when Ammonium Chloride reacts with Sodium Hydroxide in lab to form NH3 (Ammonia), NaCl (Sodium Chloride) and H2O (water). In this reaction Ammonia gas liberates. When Ammonia solution and HCl are brought together even by mistake also then they get combined with each other to form Ammonium Chloride. Ammonium Chloride comprises a strong acid, in its aqueous solution Sodium Chloride breaks to form Sodium Hydroxide and Hydro Chloric acid.
