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 ...

This makes it more dangerous because if a fire reaches it, the chemical reaction ... suddenly and the water condenses, which causes the cloud," he adds. When ammonium nitrate explodes, it can ...

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: ...
