Sodium molybdate has the advantage in that the dosing of lower ppm's of molybdate allow for lower conductivity of the circulating water. Sodium molybdate at levels of 50-100 ppm offer the same levels of corrosion inhibition as sodium nitrite at levels of 800+ ppm. By utilizing lower concentrations of sodium molybdate, conductivity is kept at a ...
The main difference between solution (1) and solution (2) is the different use of nitrate-nitrogen and ammonium-nitrogen based stock solutions to prepare the respective Hoagland solution of interest. Accordingly, the original 1933 and the modified concentrations of 1938 and 1950 for each essential element and sodium are shown below, the ...
Molybdate (usually in the form of potassium molybdate) is also used in the analytical colorimetric testing for the concentration of silica in solution, called the molybdenum blue method. [21] Additionally, it is used in the colorimetric analysis of phosphate concentration in association with the dye malachite green .
Examples of dough conditioners include ascorbic acid, distilled monoglycerides, citrate ester of monoglycerides, diglycerides, ammonium chloride, enzymes, [2] diacetyl tartaric acid ester of monoglycerides or DATEM, potassium bromate, calcium salts such as calcium iodate, L-cystine, [3] L-cysteine HCl, [4] glycerol monostearate, azodicarbonamide, [5] [6] sodium stearoyl lactylate, sucrose ...

Ammonium heptamolybdate is the inorganic compound whose chemical formula is (NH 4) 6 Mo 7 O 24, normally encountered as the tetrahydrate.A dihydrate is also known. It is a colorless solid, often referred to as ammonium paramolybdate or simply as ammonium molybdate, although "ammonium molybdate" can also refer to ammonium orthomolybdate, (NH 4) 2 MoO 4, and several other compounds.
The resulting trioxide can be purified by sublimation. The laboratory synthesis of the dihydrate entails acidification of aqueous solutions of sodium molybdate with perchloric acid: [12] Na 2 MoO 4 + H 2 O + 2 HClO 4 → MoO 3 ·2H 2 O + 2 NaClO 4. The dihydrate loses water readily to give the monohydrate. Both are bright yellow in color.
Commercial grade SSL is a mixture of sodium salts of stearoyl lactylic acids and minor proportions of other sodium salts of related acids. The HLB for SSL is 10–12. SSL is slightly hygroscopic , soluble in ethanol and in hot oil or fat, and dispersible in warm water. [ 15 ]
