Descripción general

Vanadium (IV) oxide sulfate hydrate is a blue crystalline solid. It is soluble in water and posseses weak oxidizing or reducing properties.

Aplicación

Vanadium (IV) oxide sulfate hydrate has been used to generate vanadiumions, which can be introduced in saponite clay by hydrothermal process.

VOSO4 and anthraquinone-2,7-disulfonicacid can be used as a redox couple to prepare aqueous organic redox flowbattery (AORFB) stack.

Questions

1–4 of 4 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  4. How do you calculate the degree of hydration in products 233706 and 204862?

    1 answer

    1. The equation used to determine the degree of hydration for products 233706 and 204862 is the following.((Molecular weight of Metal * Number of Metal Ions) - (% of metal in product as decimal * anhydrous weight of product)) / (% of metal in product as decimal * 18)Note: 18 is the molecular weight of water.
