 · The Gibbs free energy for the following reaction Na 2 SO 4 + 10 H 2 O > Na 2 SO 4 * 10 H 2 O can be described by ΔG = ΔH TDS = kJ/mol T (261 J/mol*K) Based on this equation, it can be estimated that the reaction reverses at 298 K or 25 o C (ΔG =0). The drying process itself is slightly exothermic (ΔH for the process is negative) but the entropy decreases during the drying ...

Blister copper, containing a minimum of % copper, is refined to high purity copper in two steps. The first step is fire refining, in which the molten blister copper is poured into a cylindrical furnace, similar in appearance to a converter, where first air and then natural gas or propane are blown through the melt to remove the last of the sulphur and any residual oxygen from the copper.

Drying of Solvents and Laboratory Chemicals

The safest method is to dry in a vacuum desicor over concentrated sulphuric acid, phosphorus pentoxide, silica gel, calcium chloride, or some other desiccant. Where substances are stable in air and melt above 100°C, drying in an air oven may be adequate. In other cases, use of an Abderhalden pistol may be satisfactory.
