The above equation describes the reaction between calcium hydroxide (Ca(OH)2) and hydrochloric acid (HCl) to form calcium chloride (CaCl2) and water (H2O).
- Reaction conditions
This reaction occurs under normal conditions, without the need for specific temperature or pressure conditions. Sufficient HCl acid should be present in excess to Ca(OH)2 for the reaction to fully occur.
- Reaction process
When calcium hydroxide comes into contact with hydrochloric acid, the reaction will immediately occur. The calcium from calcium hydroxide combines with the chloride from hydrochloric acid to form calcium chloride. Simultaneously, the hydrogen from both reactants will combine to produce water.
- Phenomena that occurs
When HCl acid is added to the Ca(OH)2 solution, a white smoke phenomenon will appear due to the dissolution process and the formation of a CaCl2 solution in water. If the reaction is complete, the solution after the reaction will not have the white precipitate phenomenon of Ca(OH)2.
