Jul 08, 2015· At the price of sodium polytungstate, its''s much better to spend the money of a good scale and make a simple SG determination rig to use with it. For RI determination, the limiting factor is the RI of the glass from which the refractometer prism is made.
H318H302H402H412: Causes serious eye damage. Harmful if swallowed. Harmful to aquatic life. Harmful to aquatic life with long lasting effects.
Recycling of sodium polytungstate. Recovery of sodium polytungstate: The polytungstate solution can be recovered by washing respective particles with distilled or demineralized / deionized water. Rinse samples repeatedly. To filter off the solids from the liquid you should use a funnel with filtration paper.
The number of electrons in each of Sodium''s shells is [2, 8, 1] and its electron configuration is [Ne] 3s sodium atom has a radius of pm and a Van der Waals radius of 227 pm. Sodium was discovered and first isolated by Sir Humphrey Davy in 1807. In its elemental form, sodium has a silverywhite metallic appearance.
Sodium polytungstate (SPT) is perfect for preparation of heavy liquids. ROTH offers an environmentally friendly alternative to using zinc chloride and mercury saline solutions or highly toxic halogenated hydrocarbons to conduct the sink or swim analyses required for density determination. Properties: Highly water soluble; pHneutral solution
When sodium polytungstate is dissolved in water, it produces a lowviscosity, transparent solution with a density up to g/cm³. The density of the solution means that solids can then be separated in it, using the sinkfloat process, for example.

In our experience, SPT (sodium polytungstate) and LMT (lithium metatungstate) are not used by many mineral labs which need a heavy liquid with a density of g/mL or more, because their solutions at these densities are too viscous. Typically the viscosity of these liquids is greater than 25 cP, or more than 25 times the viscosity of water.
