CAS 10034-82-9: Ácido crómico (H2CrO4), sal disódica, tetrahidrato

Descripción:
Ácido crómico (H2CrO4), sal disódica, tetrahidrato, comúnmente conocido como cromato de disodio tetrahidratado, es un compuesto inorgánico con la fórmula Na2CrO4·4H2O. Aparece como un sólido cristalino amarillo y es altamente soluble en agua. Este compuesto se caracteriza por sus fuertes propiedades oxidantes, principalmente debido a la presencia del ion cromato (CrO4^2-). Se utiliza a menudo en diversas aplicaciones industriales, incluyendo como inhibidor de corrosión, en procesos de tintura y en la fabricación de pigmentos. La forma tetrahidratada indica que contiene cuatro moléculas de agua por cada unidad de fórmula, lo que puede influir en su estabilidad y solubilidad. Las consideraciones de seguridad son fundamentales al manipular esta sustancia, ya que está clasificada como carcinógeno y presenta peligros ambientales. Se deben tomar las medidas de protección adecuadas para evitar la exposición, y la eliminación debe cumplir con las regulaciones sobre materiales peligrosos. En general, el cromato de disodio tetrahidratado es un compuesto significativo tanto en la investigación química como en aplicaciones industriales, pero requiere un manejo cuidadoso debido a sus propiedades toxicológicas.

  • Sodium chromate tetrahydrate, Reagent Grade

    CAS:
    Corrosion inhibitor, pigment manufactureSodium chromate tetrahydrate is used as a corrosion inhibitor, wood preservative and an auxiliary in textile industry. It serves as an oxidant, which is used to prepare carboxylic acids and ketones from primary and secondary alcohols respectively. Further, it is used as a starting material to prepare other chromium compounds and as a catalyst in organic synthesis especially pharmaceuticals and agro chemicals.

  • Sodium chromate tetrahydrate

    CAS:
    Sodium chromate is an inorganic chemical that is used as a high-resistance industrial chemical. It has a neutral pH and is often used to prepare samples for electron microscopy. Sodium chromate can also be used in the treatment of wastewater and to cross-link polymers. There are reports of carcinogenic potential, although this has not been confirmed by studies. Sodium hydroxide solution reacts with sodium chromate tetrahydrate (NaCrO4·H2O) to produce sodium carbonate (Na2CO3). This reaction occurs because the NaOH partially dissociates when it comes into contact with the NaCrO4·H2O, which produces Na+ ions and OH- ions. The OH- ions react with the Na+ ions from the NaOH to produce H2O and NaOH, which then react with more Na+.
