  • Reaction Chemistry: Determining the Molecular Formula of Calcium Hypochlorite
    Here's how to determine the molecular formula of the product formed when aqueous hypochlorous acid (HClO) reacts with aqueous calcium hydroxide (Ca(OH)₂):

    1. Identify the type of reaction:

    This is a neutralization reaction, where an acid (HClO) reacts with a base (Ca(OH)₂) to form salt and water.

    2. Write the balanced chemical equation:

    2HClO(aq) + Ca(OH)₂(aq) → Ca(ClO)₂(aq) + 2H₂O(l)

    3. Determine the molecular formula of the product:

    The product is calcium hypochlorite (Ca(ClO)₂) and water (H₂O).

    Explanation:

    * Hypochlorous acid (HClO) contributes the hypochlorite ion (ClO⁻).

    * Calcium hydroxide (Ca(OH)₂) contributes the calcium ion (Ca²⁺).

    The reaction forms calcium hypochlorite (Ca(ClO)₂) which is a salt, and water (H₂O) as a byproduct.
