What is the reaction between calcium oxide and water?
The reaction between calcium oxide and water: boiling of the solution and turbidity of the solution.Calcium oxide is what we call quicklime. Calcium oxide and water react to emit a large amount of heat, boiling the solution, producing white precipitate, calcium hydroxide, and making the solution muddy.
When the calcium oxide reacts with water to produce Ca (OH) 2, the solution is turbid because the resulting Ca (OH) 2 solubility is only about 0.16g/100g water. Clarification of the turbidity of lime water is due to the fact that the solute in it is not saturated or just saturated and the solute does not precipitate. The knowledge of dissolution and heat release, when dissolved, is divided into ionization and hydration, the process of ionization is endothermic, and the hydration process is exothermic. The amount of heat released by the hydration process is greater than that absorbed by the ionization process, which is exothermic, and vice versa.
Calcium oxide (calcium oxide), is a kind of inorganic compounds, its chemical formula is CaO, the name of lime. Physical properties are white powder surface, impure is gray, containing impurities when pale yellow or gray, with moisture absorption. Calcium oxide is an alkaline oxide, sensitive to humidity. Easy to absorb carbon dioxide and moisture from the air. Reacts with water to produce calcium hydroxide (Ca (OH) 2) and produces a large amount of heat and is corrosive.
