WebJan 23, 2024 · If you add sodium hydroxide solution to an unknown organic compound, and it gives off ammonia on heating (but not immediately in the cold), then it is an amide. You can recognize the ammonia by smell and because it turns red litmus paper blue. The possible confusion using this test is with ammonium salts. Sodium hydroxide also reacts with acidic oxides, such as sulfur dioxide. Such reactions are often used to "scrub" harmful acidic gases (like SO2 and H2S) produced in the burning of coal and thus prevent their release into the atmosphere. For example, 2 NaOH + SO2 → Na2SO3 + H2O Reaction with metals … See more Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH.
