Two dry solids --- barium hydroxide and ammonium nitrate --- are mixed to produce an endothermic reaction. The temperature of the mixture drops approximately 45oC and is cold enough to freeze the ...

Endothermic reactions include solid citric acid and sodium hydrogencarbonate, and dissolving ammonium nitrate in water. Demonstrate a spectacular reaction such as the thermite reaction or the ...

ammonium nitrate and ammonium sulfate – can be identified by heating a solution of the ions with sodium hydroxide. This reaction produces ammonia gas, as shown in the ionic equation below: ...
