MEJORAS EN UNA SOLUCION ACUOSA ESTABILIZADA DE DITIONITA DE SODIO Y SULFITO DE SODIO

摘要

Aqueous solutions containing mixtures of sodium dithionite and sodium sulfite having concentrations of greater than 13 percent by weight of Na2S2O4 are stabilized by adding potassium hydroxide in an amount which is sufficient to provide a residual of from about 1 to about 12 grams per liter of solution. These solutions can be stored at temperatures of from about 0 DEG to about 15 DEG C. without crystallization taking place.
