1\u3001Propiedades del producto<\/b><\/strong><\/h4>\n

El nitrito de sodio se presenta en forma de polvo o gr\u00e1nulos cristalinos de color blanco a amarillento, inodoros y con un sabor ligeramente salado. Muy soluble en agua (82g\/100mL a 20\u00b0C) y amon\u00edaco l\u00edquido, poco soluble en etanol\/metanol. Su soluci\u00f3n acuosa es alcalina (pH~9). Se descompone t\u00e9rmicamente a 320\u00b0C, liberando \u00f3xidos de nitr\u00f3geno t\u00f3xicos. Se oxida gradualmente en el aire para formar nitrato de sodio.<\/p>\n

3. \u00c1mbito de aplicaci\u00f3n y uso<\/b><\/strong><\/h4>\n

El nitrito de sodio tiene una amplia gama de usos. Como aditivo alimentario, el nitrito de sodio (NaNO2) tiene funciones de inhibici\u00f3n de bacterias, desarrollo del color, antioxidaci\u00f3n y mejora del sabor, y se utiliza ampliamente en la conservaci\u00f3n de productos c\u00e1rnicos. Adem\u00e1s de utilizarse como conservante alimentario, tambi\u00e9n es un excelente fijador del color y potenciador del sabor de los productos c\u00e1rnicos, especialmente aplicado en la industria del curado de la carne. El nitrito s\u00f3dico tambi\u00e9n puede utilizarse como agente anticorrosivo en la industria de fabricaci\u00f3n de productos de acero y como coagulante en la industria de la construcci\u00f3n. El nitrito s\u00f3dico tambi\u00e9n es un inhibidor de la corrosi\u00f3n an\u00f3dica y se utiliza mucho en la industria de la maquinaria. El nitrito s\u00f3dico reacciona con la superficie del metal formando una densa pel\u00edcula de \u00f3xido sobre ella. Esta capa protectora dificulta la ionizaci\u00f3n de la capa met\u00e1lica interior y suprime la reacci\u00f3n electroqu\u00edmica an\u00f3dica, ralentizando as\u00ed la corrosi\u00f3n electroqu\u00edmica del metal.<\/p>\n
