Detailed information about the equation BaS + 2HNO3 -> Ba(NO3)2 + 2H2O + S:
- BaS is the chemical formula of Barium sulfide, a white, odorless, tasteless, and highly toxic solid.
- HNO3 is nitric acid, a pale yellow, strong, and toxic liquid.
- Ba(NO3)2 is Barium nitrate, a white, odorless, tasteless, and toxic solid.
- H2O is the chemical formula for water.
- S is the chemical symbol for sulfur, a yellow solid.
-
Reaction conditions:
- The reaction occurs at normal temperature.
- An adequate amount of HNO3 must be ensured to react with BaS.
-
Reaction process:
- Barium sulfide reacts with nitric acid to form barium nitrate, water, and sulfur.
-
Occurring phenomena:
- When the reaction occurs, you will see the phenomenon of gas bubbling. The white solid (BaS) will gradually dissolve and the white solid (Ba(NO3)2) will appear along with yellow sulfur.
