Verified answer
3) Ammonium hydroxide.
When ammonium chloride is heated it undergoes dissociation to form a product such as NH3 and HCl. The ammonium chloride undergoes sublimation when it is heated, substance changes from solid to gas. The gas contains molecules such as ammonia and hydrogen chloride.
Ammonia is basic in nature and turns red litmus blue.
Hydrogen chloride when mixed with water makes an acidic solution
