Sodium nitrite and Hydrochloric acid Reaction | NaNO2 + HCl
Sodium nitrite and Hydrochloric acid Reaction | NaNO 2 + HCl. Aqueous sodium nitrite (NaNO 2) reacts with cold dilute hydrochloric acid (HCl) and gives nitrous acid (HNO 2) and sodium chloride (NaCl). This reaction is used to prepare nitrous acid.
Reactions of Diazonium Salts: Sandmeyer and Related Reactions
2018年12月3日 · The second key reagent is a strong mineral acid like HCl; if NaNO 2 is used, HCl converts it into HNO 2. The key purpose of HCl is to further convert HNO 2 into the powerful electrophile NO +, the “nitrosonium ion“, which is the key electrophile in …

2023年1月23日 · The reactions of nitrous acid with 1°- and 2°- aliphatic amines may be explained by considering their behavior with the nitrosonium cation, NO (+), an electrophilic species present in acidic nitrous acid solutions.
The Reaction of Amines with Nitrous Acid - Chemistry LibreTexts
2023年1月23日 · In each of the following reactions, the amine would be acidified with hydrochloric acid and a solution of sodium or potassium nitrite added. The acid and the nitrite form nitrous acid which then reacts with the amine.
17.3: Reactions involving arenediazonium salts
The acid reacts with the NaNO 2 to form nitrous acid (HNO 2), which then reacts with the arylamine to form the arenediazonium salt. The most common salt to use for these reactions is the chloride (made using HCl as the acid), which are fairly soluble but decompose rapidly at …
Sodium nitrite - Wikipedia
In meat processing, sodium nitrite is never used in a pure state but always mixed with common salt. This mixture is known as nitrited salt, curing salt or nitrited curing salt. In Europe, nitrited curing salt contains between 99.1% and 99.5% common salt and between 0.5% and 0.9% nitrite.
