In the reaction, represented by Na2CO3 + HC1 → NaHO3 + NaCl, the equivalent weight of Na2CO3 is________________?
Correct answer: C. 106
- A. 53
- B. 5.3
- C. 106
- D. 10.6
Explanation
The intended product is NaHCO₃, representing the first neutralization step in which one mole of Na₂CO₃ accepts one mole of H⁺. Its equivalent weight is therefore 106/1 = 106, whereas 53 applies to complete neutralization to carbonic acid or CO₂.
