Which salt is formed in the reaction between sodium hydrogen carbonate and hydrochloric acid?
Answer and explanation
Correct answer: Sodium chloride
The governing concept is the formation of a salt from the ions supplied by the reactants. In the reaction NaHCO₃ + HCl → NaCl + H₂O + CO₂, sodium combines with chloride to form sodium chloride. Therefore option B is correct. Sodium sulphate would require sulphate ions, while calcium carbonate and magnesium chloride require ions not present in these reactants.
