The chemical equation Ca(OH)2 + H2SO4 -> CaSO4 + 2H2O

  1. Detailed information about the equation Ca(OH)2 + H2SO4 -> CaSO4 + 2H2O:

  • Ca(OH)2 is Calcium hydroxide, also known as slaked lime. Under normal conditions, Ca(OH)2 is a solid, white and odorless substance.

  • H2SO4 is Sulfuric acid, known as one of the strongest acids. H2SO4 is a colorless liquid with a distinctive smell.

  • CaSO4 is Calcium sulfate, a white, odorless, tasteless solid that is insoluble in water.

  • H2O is water, a colorless, odorless liquid.

  1. Reaction conditions:
  • This reaction occurs easily at room temperature.
  1. Reaction process:
  • During the reaction process, Calcium hydroxide (Ca(OH)2) reacts with Sulfuric acid (H2SO4) to produce Calcium sulfate (CaSO4) and water (H2O).
  1. Phenomenon occurs:
  • When Ca(OH)2 reacts with H2SO4, there will be a bubbling phenomenon if the reaction takes place in solution. At the same time, it will create a precipitate of Calcium sulfate. This is an acid-base neutralization reaction.
