FAQS on na2s2o3 kio3
Q: What is the role of Na2S2O3 and KIO3 in iodometric titrations?
A: Na2S2O3 (sodium thiosulfate) acts as a reducing agent to titrate iodine (I2) generated by KIO3 (potassium iodate) in acidic conditions. KIO3 serves as an oxidizing agent, releasing iodine during the reaction. This method is widely used to determine oxidizing agents quantitatively.
Q: How does Na2S2O3 react with I2 in chemical experiments?
A: Na2S2O3 reacts with I2 to form sodium tetrathionate (Na2S4O6) and sodium iodide (NaI). The balanced equation is: 2Na2S2O3 + I2 → Na2S4O6 + 2NaI. This reaction is central to iodometric titration for quantifying iodine concentrations.
Q: Why is Na2S2O3 pentahydrate commonly used in laboratories?
A: Na2S2O3 pentahydrate is a stable, crystalline form of sodium thiosulfate, making it easier to handle and store. It dissolves readily in water to prepare standardized solutions. Its stability ensures consistent results in redox reactions and photography development.
Q: Can Na2S2O3 and KIO3 be used together in a redox reaction?
A: Yes, KIO3 oxidizes Na2S2O3 in acidic media, producing iodine (I2) and sulfate ions. The reaction is time-dependent and often used in "iodine clock" experiments to study reaction kinetics. Precise stoichiometry is critical for accurate results.
Q: How to prepare a stable Na2S2O3 solution for titrations?
A: Dissolve Na2S2O3 pentahydrate in freshly boiled, cooled distilled water to minimize microbial degradation. Store the solution in a dark bottle to prevent light-induced decomposition. Standardize it against a KIO3 solution for accuracy.
