Use of Conventional Drying Agents

2016321 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 = 778 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
