    Na⁺ and HCO⁻₃

    Explanation:

    When baking soda is dissolve in water it fully ionized into positive and negative ions.

    NaHCO₃ + H₂O → Na⁺ + HCO⁻₃

    The Na⁺ than react with OH⁻ of water and produced NaOH while HCO⁻₃ react with H⁺ and produce H₂CO₃. This carbonic acid than break to produced carbon dioxide and water.

    H₂CO₃ → H₂O + CO₂

    Properties of baking soda:

    It is odorless compound.

    It is solid at room temperature.
