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.

It is used in medicine to cure the acidity of stomach.

It is used to make baking powder.
