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. -
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. -
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)
- 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.
