How do you make sodium metavanadate?

How do you make sodium metavanadate?

Na3VO4 Stock Solution Prepare a stock solution of 200 mm sodium orthovanadate (Na3VO4). Adjust the pH of the 200 mm stock solution to 10 using 1 n NaOH or 1 n HCl. (At a pH of 10 the solution should be yellow.) Boil until the solution clears (~10 min).

What is sodium metavanadate used for?

Sodium metavanadate (SMV) is a vanadium salt that can be used as a corrosion inhibitor with good inhibition efficiency (98%) at 200 ppm. It can be used in the protection of carbon steel.

Why is there vanadium in my multivitamin?

Vanadium supplements are used as medicine. Vanadium is used for treating diabetes, low blood sugar, high cholesterol, heart disease, tuberculosis, syphilis, a form of “tired blood” (anemia), and water retention (edema); for improving athletic performance in weight training; and for preventing cancer.

How do you make 200mm sodium orthovanadate?

1) Prepare a solution of 200 mM sodium orthovanadate in ultrapure dH20 according to protocol by Gordon (1991) PubMed. For a 100 mL solution, add 3.68 g Na3VO4 to 90 mL water and dissolve with stirring. Once dissolved, bring volume to 100 mL.

What kind of inhibitor is vanadate?

competitive inhibitor
Sodium Orthovanadate (Vanadate, Na3VO4) is a commonly used general inhibitor for protein phosphotyrosyl phosphatases (PTPs). It is a competitive inhibitor. The inhibition by Vanadate is completely reversible upon the addition of EDTA or by dilution.

What is another name for vanadium?

Other Name(s): Atomic number 23, Metavanadate, Métavanadate, Orthovanadate, Pentoxyde de Vanadium, Sulfate de Vanadyl, V, Vanadate, Vanadio, Vanadium Pentoxide, Vanadyl, Vanadyl Nicotinate, Vanadyl Sulfate, Vanadyl Sulphate.

How do you make sodium fluoride solution?

Weigh and transfer 0.2210 g of sodium fluoride to a 1 liter volumetric flask. Dissolve in distilled water and bring to volume. This solution contains 100 µg of fluoride ion per ml. The solution is stable for one year when stored in a plastic bottle.
