Reaction rate, Photo 1 of 2. Baking soda and washing soda reacting with acid. A 0.1M solution of hydrochloric acid (HCl) is added to few grams of solid washing soda, NaCO3 (Photo 1) and few grams of baking soda, NaHCO3 (Photo 2). Carbon dioxide bubbles are produced in both reactions. The first reaction proceeds less vigorously than the second reaction, as it requires 2 molecules of HCl to produce 1 molecule of CO2, while the second reaction requires 1 molecule of HCl to produce 1 molecule of CO2. The balanced reactions are: Na2CO3 + 2HCl -> 2NaCl + H2O + CO2 and NaHCO3 + HCl -> NaCl + H2O + CO2. | |
