The products of the reaction between dilute sulphuric acid and sodium thiosulphate crystals are?
- Na2SO4 + SO2 + O2 + H2O
- Na2SO3 + SO3 + O2 + H2O
-
Na2SO4 + SO2 + S + H2O
- Na2SO4 + SO3 + S + H2O
- Na2SO4 + SO2 + H2O only
The correct answer is: C
Explanation
\(Na_2S_2O_3 + H_2SO_4 → Na_2SO_4 + SO_2 + S↓ + H_2O\). Sodium thiosulfate reacts with sulfuric acid to produce sodium sulfate, sulphur dioxide, sulfur, and water.
