L'ossido di calcio viene inserito nel fondo della lattina, la pressione di una membrana sul fondo miscela l'ossido di calcio con l'acqua e la reazione esotermica scalda la bevanda. Sodium sulfide is the chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S·9H 2 O.Both the anhydrous and the hydrated salts are colorless solids. They are water-soluble, giving strongly alkaline solutions. When exposed to moist air, Na 2 S and its hydrates emit hydrogen sulfide, which smells like rotten eggs.Some commercial samples are specified as Na 2 S·xH 2 O Il solfato di calcio è il sale di calcio dell'acido solforico..

Come per altri sali che contengono ioni solfuro, il solfuro di calcio emette un odore tipico di H 2 S, a causa delle piccole quantità di sale che si idrolizzano a contatto con l'umidità dell'aria. CaO + H 2 O → Ca(OH) 2 + 1 136 kJ /kg di CaO. Questa reazione viene utilizzata spesso per produrre bevande in lattina calde.
