Sodium sulphate reacts with potassium chloride to give glaserite, a double salt of sodium sulphate and potassium sulphate. Sodium sulphate present in Sambhar brines and solid bittern crust of Sambhar Salts Ltd, Nawa has been converted to glaserite at ambient temperature. Preparation and recovery of glaserite and potassium sulphate have been discussed using Lowenherz's projections based on the ...

Heparan sulphate (HS), a ubiquitous glycosaminoglycan, is a polymer of Dglucuronic acid or Liduronic acid and Dglucosamine (GlcA) sugars. It is synthesized in the cisGolgi as Golgi, final heparan sulphate is synthesized in by the action of enzymes N and OHSsulphotransferases and HS mature HS has 50 to 200 disaccharide units.
Prepare a M stock solution of sodium cacodylate in water ( g/100 ml). Add the following amounts of M HCl per 100 ml cacodylate stock solution, followed by the addition of DI to a final volume of 400 ml, to obtain M cacodylate buffer at the desired pH (Dawes, 1971).

Sodium sulfate may be used for precipitation of IgG instead of ammonium sulfate. The advantage of the sodium salt is that a purer preparation of IgG can be obtained, but this
In this study, the effect of sodium sulfate on preparation of ferronickel from nickel laterite by carbothermal reduction was investigated. The thermodynamic analysis showed that the addition of sodium sulfate can effectively enlarge the region of liquid slag in the phase diagram.
Preparation of Sodium Phosphate Buffers 1) In a beaker pipette aliquots of 1M stock solutions according to the desired pH of your buffer (see table below). 2) Add water to bring the volume to approximately 45 mL. 3) Measure the pH of the solution. If it is below the desired pH add NaOH to raise it to the correct pH. If it is above the desired pH add phosphoric acid to lower it to the desired

Calculate the mass of sodium sulphate required to prepare its 20% (mass percent) solution in 100 g of water?
· preparing insoluble barium sulfate salt. Barium sulfate salt is made of Ba2+ ions and SO42 ions. So, we have to prepare two soluble salts solutions of which one contains Ba2+, its positive metal ions and the other contains the SO42, its negative nonmetal ions. These two ions will react and form a precipitation as barium sulfate salt.
