The equation NaHCO3 + HCl -> NaCl + H2O + CO2

Detailed Information about the equation NaHCO₃ + HCl -> NaCl + H₂O + CO₂

• In this equation, NaHCO₃ (bicarbonate of soda or baking soda) reacts with HCl (hydrochloric acid) to form NaCl (table salt), H₂O (water), and CO₂ (carbon dioxide gas).
• The reactants and the products formed are all in the ionic form because this is an ionic exchange reaction.

Reaction Conditions

• The reaction can occur at room temperature and standard pressure.
• Although a catalyst is not required, the reaction can be accelerated by increasing the temperature or pressure.
• The reaction needs to be performed in an acidic environment due to HCl.

Reaction Process

• When NaHCO₃ and HCl are mixed together, they will create a solution containing sodium, chloride, water, and carbon dioxide gas.
• The sodium ions from NaHCO₃ and the chloride ions from HCl will combine to form sodium chloride (NaCl), also known as table salt.
• Meanwhile, the remaining hydrogen and carbonate ions will combine to form water (H₂O) and carbon dioxide gas (CO₂).

Phenomena Occurred

• When the reaction takes place, we will see bubbles of CO₂ gas escaping. This is the phenomenon of carbon dioxide gas starting to escape from the solution.
• If the reaction is carried out in a sealed container, we may see the pressure inside the container increasing due to the release of CO₂ gas.
• Also, a white solid substance (table salt) will also appear in the solution.
