Mannheim: 2 NaCl + H 2 SO 4 → 2 HCl + Na 2 SO 4 Hargreaves: 4 NaCl + 2 SO 2 + O 2 + 2 H 2 O → 4 HCl + 2 Na 2 SO 4 The second major production of sodium sulfate are the processes where surplus sodium hydroxide is neutralised by sulfuric acid to obtain sulfate ( SO 2− 4 ) by using copper sulfate (CuSO 4 ) (as historically applied on a large ...

Thénardite is an anhydrous sodium sulfate mineral, Na 2 SO 4 which occurs in arid evaporite environments, specifically lakes and playas. It also occurs in dry caves and old mine workings as an efflorescence and as a crusty sublimate deposit around fumaroles .
Here, is the amount of the solute in moles, [4] is the number of constituent particles present in volume (in litres) of the solution, and is the Avogadro constant, since 2019 defined as exactly 6.022 140 76 × 10 23 mol −1.

The SI unit of molar conductivity is siemens metres squared per mole (S m 2 mol −1). [2] However, values are often quoted in S cm 2 mol −1 . [ 4 ] In these last units, the value of Λ m may be understood as the conductance of a volume of solution between parallel plate electrodes one centimeter apart and of sufficient area so that the ...
