    The second key reagent is a strong mineral acid like HCl; if NaNO2 is used, HCl converts it into HNO2. The key purpose of HCl is to further convert HNO2 into the powerful electrophile NO+, the “nitrosonium ion“, which is the key electrophile in the reaction that forms the diazonium salt.

    Since nitrous acid is unstable, as a result it is generated in situ by treatment of sodium nitrite with strong acid such as HCl or H2SO4.
