Reaction between Na2S2O3 and Cl2:

- The reaction between Na2S2O3 (sodium thiosulfate) and Cl2 (chlorine gas) results in the formation of NaHSO4 (sodium bisulfate) as the product.
- The balanced chemical equation for the reaction is as follows:
Na2S2O3 + Cl2 → 2NaHSO4 + S

Explanation:

- Sodium thiosulfate (Na2S2O3) is a compound that contains sodium ions (Na+) and thiosulfate ions (S2O3^2-).
- Chlorine gas (Cl2) is a diatomic molecule consisting of two chlorine atoms.
- When these two compounds react, the chlorine gas oxidizes the thiosulfate ions present in the sodium thiosulfate.
- The chlorine gas is reduced to chloride ions (Cl-) while the thiosulfate ions are oxidized to sulfate ions (SO4^2-).
- The sodium ions remain unchanged in the reaction.
- The balanced equation for the reaction shows that two molecules of sodium thiosulfate react with one molecule of chlorine gas to produce two molecules of sodium bisulfate and elemental sulfur.
- The sodium bisulfate (NaHSO4) is the main product of the reaction, while the sulfur (S) is a byproduct.
- Thus, the correct answer is option 'A' which states that the reaction between Na2S2O3 and Cl2 produces NaHSO4.

Overall Reaction:

Na2S2O3 + Cl2 → 2NaHSO4 + S
