Preparation Of Ammonium Hydroxide ( NH₄OH )

Preparation Of Ammonium Hydroxide ( NH₄OH ) From Urea And Sodium Hydroxide. Warning: contact can severely irritate and burn the skin and eyes leading to eye damage. ► Exposure can irritate the eyes, nose and throat. ► Inhaling Ammonium Hydroxide can irritate the lungs. Higher exposures may cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency. Process: first measure 30 ml of distilled water then add 4g of sodium hydroxide in it. now add 5g of urea in the bottle and place it on hot plate now add solution of sodium hydroxide in it and close the cap of the the bottle and place the the tube in the test tube containing 10ml of distilled now start heating it up after 5 or 10 minutes it start producing ammonia gas. now wait for one hour to complete the reaction when the reaction is almost complete then remove the tube because it can cause back flow. Information: Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH₃.
