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

  1. Detailed Information about the Equation CaO + H2O -> Ca(OH)2
    The above chemical equation depicts the reaction between calcium oxide (CaO), commonly known as quicklime, and water (H2O) to produce calcium hydroxide (Ca(OH)2), also known as slaked lime.

  2. Reaction Conditions
    This reaction occurs under normal temperature and pressure conditions. Quicklime reacts with water to produce slaked lime, a heat-releasing reaction, increasing the reaction temperature.

  3. Reaction Process
    Introducing quicklime (CaO) into water, it reacts vigorously with water to form slaked lime (Ca(OH)2) and releases heat.

CaO + H2O -> Ca(OH)2 + Q (Q is the heat released during the reaction)

  1. Phenomena Occurrence
    When quicklime (CaO) is added to water, gas bubbles are vigorously released, the water heats up and forms a slaked lime solution (Ca(OH)2). After the reaction, the solution reacts with litmus paper, changing the paper color from blue to red, indicating that the solution is basic in nature.
