Physical and chemical properties of sodium sulfate

Sodium sulfate is the sodium salt of sulfuric acid. It is a white crystalline solid of formula Na2SO4 which is known as the mineral thenardite when it is in a situation of anhydrous. I think drainage agent supplier may be got a better understanding for this as drainage agent, to some extent, has the same properties with sodium sulfate.

Today, let’s have a look at the physical and chemical properties of sodium sulfate. Sodium sulfate is very stable chemically, being unreactive toward most oxidizing or reducing agents at normal temperatures. It can be converted to sodium sulfide by carbothermal reduction Na2SO4 + 2 C → Na2S + 2 CO2 at high temperatures. What’s more, sodium sulfate is a neutral salt, which forms aqueous solutions with pH of 7. The neutrality of such solutions reflects the fact that sulfates is derived, formally, from the strong acid sulfuric acid. Furthermore, the Na+ ion, with only a single positive charge, only weakly polarizes its water ligands provided there are metal ions in solution. It is different from the products silicon products which could buy in high quality silicon iron alloy cored wires wholesale. Finally, its solubility in water rises more than tenfold between 0 °C to 32.384 °C, where it reaches a maximum of 497 g/L. At this point, the solubility curve changes slope, and the solubility becomes almost independent of temperature. This temperature at 32.384 °C, corresponding to the release of crystal water and melting of the hydrated salt, serves as an accurate temperature reference for thermometer calibration.

If you have interest in chemical products, actually, you can buy them and do some simple research on them. It is a nice choice to buy best PVC in Chinaas they are cheap products with high quality.
