    Calcium Oxide (CaO): Base or Acid? Understanding Its Properties
    Calcium oxide (CaO) is a base. Here's why:

    * Metal oxides: Metal oxides generally form bases when they react with water.

    * Calcium: Calcium is a metal.

    * Reaction with water: Calcium oxide reacts with water to form calcium hydroxide (Ca(OH)2), which is a strong base.

    CaO + H2O → Ca(OH)2

    Therefore, calcium oxide is considered a basic oxide.
