  Survey of Nitrogen Compounds and their Uses:- Nitrogen compounds play an important role in many aspects of life and  commercial processes, from the industrial production of fertilizers to the building blocks of life. The nitrogen-nitrogen triple bond in N 2 contains 226 kcal/mol of  energy, making it one of the strongest bonds known. When nitrogen gas is formed as a product from various reactions, the bond energy associated with the N-N triple bond is released, causing the explosive properties seen in many nitrogen compounds. Amines The main neutral hydride of nitrogen is ammonia (NH 3 ), although hydrazine (N 2 H 4 ) is also commonly used. Ammonia is more basic than water by 6 orders of magnitude. In solution, ammonia forms the ammonium ion (NH 4 + ). The pK a of ammonium chloride is 9.2. Liquid ammonia (boiling point 240 K i.e. -33 degree C) is amphiprotic  (displaying either Brønsted-Lowry acidic or basic character) and forms  ammonium and the l...

Boric acid cannot be titrated directly with NaOH (Sodim Hydroxide) because the end point is not sharp it undergoes excessive hydrolysis to give break H3BO3 and NaOH Reaction:-  H3BO3 + NaOH ------ Na(B(OH)4)------NaBO2 + 2H2O Formic and oxalic acid are samething both having same COOH group Oxalic acid and formic acid directly titrated with NaOH by using Acid-Base titration with the help of the phenopthalein indicator which change the color Colorless to Pink.         So Boric acid can titrated with the help of polyhroxy compound i.e- Catechol,Manitol.  Ad just to show  Skin id here-  https://drive.google.com/file/d/1viYFePMG8g-6xQT3umezWyB83cb7lRTT/view?usp=drivesdk

Because endpoint is not sharp it undergoes excessive hydrolysis to give back H3BO3 and NaOH.  So we use polyhydroxy compound to detect the endpoint like catechol. 

  DEODORANTS AND ANTIPERSPIRANTS -  A Deodorant is a substance applied to the body to prevent or mask body odour due to bacterial breakdown of perspiration in the armpits, groin, feet and other parts of the body. Antiperspirants are a subclass of deodorants. They prevent sweating typically by blocking sweat glands. Antiperspirants are used on a  wider range of body parts, at any place where sweat would be inconvenient or unsafe, since unwanted sweating can interfere with comfort, vision, and grip (due to slipping). Deodorants allow sweating but prevent bacterial action on sweat, since human sweat only has a noticeable smell when it is decomposed by bacteria while the antiperspirants prevent sweating. Most of the early antiperspirants were made with aluminium salts, with aluminium sulphate and alum being most commonly employed. If scented diethylene glycol ether could be added to help incorporate the perfume into the mixture giving the final product some additional odou...
