The reaction equation CaS + 2H2O2 -> CaSO4 + 2H2O can be translated into English as follows: Calcium sulfide reacts with hydrogen peroxide to produce calcium sulfate and water.

  1. Detailed information on the equation CaS + 2H2O2 -> CaSO4 + 2H2O:
    This equation describes a chemical reaction process between calcium sulfide (CaS) and hydrogen peroxide (H2O2) to yield calcium sulfate (CaSO4) and water (H2O).

  2. Reaction conditions:
    This reaction usually occurs under normal temperature and pressure conditions. However, the reaction rate can be accelerated if the temperature is increased.

  3. Reaction process:
    The reaction begins when calcium sulfide and hydrogen peroxide come into contact with each other. Calcium sulfide reacts with hydrogen peroxide, a strong oxidizing agent, to form calcium sulfate and water.

  4. Phenomena that occur:
    During the reaction process, you may see gas bubbles rising from the solution. This is the water produced in the reaction. Simultaneously, calcium sulfate, a solid substance, will also be formed and reside at the bottom of the reaction vessel.
