Le composé hydrosulfité peut être un dianion d'hydrosulfite produit en intermédiaire lorsqu'on utilise le dioxyde de thiourée comme matériau de départ dans la solution.

The dithionite compound may be a dithionite dianion which is produced as an intermediary when thiourea dioxide is used as a starting material in the solution.

Le dioxyde de thiourée n'est pas un dioxyde, mais est plutôt un dérivé d'un acide sulfinique (RS (O) (OH), d'où le nom alternatif acide formamidine sulfinique.

Thiourea dioxide is not a dioxide, but instead is a derivative of a sulfinic acid (RS(O)(OH), hence the alternative name formamidine sulfinic acid.

Ceci est accompli en chauffant le colorant dans une solution fortement basique d`hydroxyde de sodium (lessive) ou de carbonate de sodium (potasse caustique) contenant un agent réducteur tel que l`hydrosulfite de sodium ou le dioxyde de thiourée.

This is accomplished by heating the dye in a strongly basic solution of sodium hydroxide (lye) or sodium carbonate (caustic potash) containing a reducing agent such as sodium hydrosulfite or thiourea dioxide.
