The equation because that this endothermic reaction is provided as:

Ba(OH)2.8H2O(solid) + 2 NH4SCN(solid) → Ba(SCN)2(s ) + 10 H2O(liquid) + 2 NH3(gaseous).

This is an endothermic reaction that absorbs warm from the environment. This leads to a rapid drop in the temperature that this reaction, which can be check out with the help of a digital thermometer. It provides the beaker frozen to the wooden board. This is the factor why the beaker have to be rest on a tiny board v a couple of drops that water poured ~ above it.
