ENDOTHERMIC REACTION: Ba(OH)2.8H2O & NH4SCN<br />
Barium Hydroxide and Ammonium Thiocyanate<br />
The solids barium hydroxide & ammonium thiocyanate are mixed at room temperature. The temperature drops to below zero deg C. in the endothermic reaction:  Ba(OH)2.8H2O(s) + 2NH4SCN(s) -> Ba(SCN)2.2H2O(s) + 2NH3(aq) + 8H2O.
