Question

Equations for the Standardization of the Na2S2O3 (aq): 

KIO3(aq) + 5KI(aq) + 3 H2SO4(aq) → 3 I2(aq) + 3 H2O(l) + 3K2SO4(aq)

I2(aq) + 2 Na2S2O3(aq) → 2 NaI(aq) + Na2S4O6(aq) 

Equations for the Titration of the NaOCl (aq):

NaOCl(aq) + H2O(l) + 2 KI(aq) → NaCl(aq) + 2 KOH(aq) + I2(aq)

I2(aq) + 2 Na2S2O3(aq) → 2 NaI(aq) + Na2S4O6(aq) 

This table presents the key components of three distinct chemical reactions, specifically focusing on the elements involved and the electron transfer processes. Here is the structure of the table: ### Reaction Analysis Table | Reaction type | **KIO₃ reaction** (first one) | **Na₂S₂O₃ reaction** (second one) | **NaOCl reaction** (third one) | |------------------------------|----------------------------------|-----------------------------------|----------------------------------| | **Oxidized element** | | | | | **Reduced element** | | | | | **Electrons transferred** | | | | ### Explanation: 1. **KIO₃ Reaction (First One):** - This column is dedicated to understanding the redox changes during the KIO₃ reaction. It highlights which element is oxidized, which is reduced, and the number of electrons exchanged. 2. **Na₂S₂O₃ Reaction (Second One):** - Similar to the KIO₃ reaction, this column examines the redox process in the Na₂S₂O₃ reaction. It pinpoints the oxidized and reduced elements and provides electron transfer data. 3. **NaOCl Reaction (Third One):** - This section evaluates the redox changes in the NaOCl reaction, detailing the elements involved in oxidation and reduction along with electron transfer information. This table serves as a quick reference for comparing the redox characteristics of the three reactions by outlining which elements participate in oxidation and reduction and quantifying the electrons transferred during each reaction.
