Answer:
Step-by-step explanation:
The acid-base reaction between hydrochloric acid (HCl) and sodium bicarbonate (NaHCO3) to give sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2) is not a redox reaction.
In a redox reaction, there is a transfer of electrons between the reactants. In this acid-base reaction, there is no transfer of electrons. The reaction involves the transfer of a proton (H+) from the HCl to the bicarbonate ion (HCO3-), forming carbonic acid (H2CO3), which then decomposes into water and carbon dioxide. The remaining sodium ion (Na+) combines with the chloride ion (Cl-) to form NaCl.
Therefore, the acid-base reaction of HCl and NaHCO3 is not a redox reaction, but rather a type of chemical reaction called a neutralization reaction.
