Source sentences:
text: With primary amines nitrous acid results in evolution of nitrogen gas; with secondary amines insoluble yellow liquids or solid \(\ce{N}\)-nitroso compounds, \(\ce{R_2N-N=O}\), separate; tertiary alkanamines dissolve in and react with nitrous acid solutions without evolution of nitrogen, usually to give complex products: Nitrous acid is unstable and always is prepared as needed, usually by mixing a solution of sodium nitrite, \(\ce{NaNO_2}\), with a strong acid at \(0^\text{o}\).
text: Nitrous acid is an unstable molecule and decomposes readily in solution by either one of these pathways.
text: Nitrous acid (HNO 2 ), a weak acid, is very unstable and exists only in aqueous solution.
text: Nitrous acid is unstable and prepared always in situ and written as HONO to represent its structure.
text: Nitrous acid is unstable, and only exists in the form of solutions which gradually degrade after several minutes.
