The oxidizing agent is "I"_2. ); The Gold Parsing System (Hats off! Click hereto get an answer to your question ️ In the reaction, I2 + 2S2O3^2 - → 2I^- + S4O6^2 - , equivalent mass of iodine is: Please register to post comments. I2 + 2(S2O3)2→2I- + (S4O6)2- All I can answer is that 1mol of I2 reacts with 2mol of (S2O3)2 Question: Balance: IO3^-+S2O3^2- -> I2 + S4O6^2-This problem has been solved! Question. Because you have three oxygen atoms, the oxidation number is now -2 … In this case, you're going from a neutral molecule to a negatively charged ion, so right from the start, you know that iodine is being reduced, i.e. I have the Ionic equations as : Cu^2+ + e- =>> Cu^1+ 2s2o3^2- =>> s4o6^2- … Equation 2: 2s2o3^2- + I2 =>> 2I^1- + s4o6^2-I am not quite sure what to do here? Break down the elements in the compound: Oxygen's normal oxidation number is -2. Question: In The Reaction 2S2O3^2- + I2 --> 2I^- + S4O6^2-how Do I Calculate The Moles Of 2S2O3^2- Produced In The Reaction Knowing4.0 Ml Of Dionized Water, 1.0 Ml Of Buffer, 1.0 Ml Of 0.3M KI, 1.0 Ml Of 0.02M Na2S2O3, And 0.1M H2O2 React? What a great software product!) The net result is that you lose 2 electrons, thus the reaction is: 2 (S2O3)2- ----> (S4O6)2- + 2 e-The oxygens are balanced on both sides, so this half-reaction is completely balanced. s2o3 (2-)/s4o6 (2-) Pour obtenir l'équation de la réaction d'oxydoréduction, il faut pas à pas suivre toujours les mêmes étapes (donc si vous connaissez les étapes à suivre l'obtention de l'équation ne présente pas de difficultés insurmontable) Therefore, we add an 5 H2O so each H2O contributes an oxygen to make it 8 oxygens on the reactant side and 8 on the product side. As each mole KIO3 contains 1 mole IO3-, there will be w moles of IO3-Go to first equation IO3- + 5I- + 6H+ ---> 3I2 + 3H2O I 2 + 2 S 2 O 3 2 − → 2 I − + S 4 O 6 2 − In the above reaction I 2 is converted to I − where the oxidation state changed from 0 to -1 So equivalent weight of iodine will be equal to molecular weight/1. A quick technique to use here would be to look at the fact that you're going from iodine, "I"_2, on the reactants' side to the iodide anion, "I"^(-), on the products' side. The reason we had a 5 H2O is because we see that S2O3 has 3 O's but it needs to balance with the 8 O's on the products side. S 2 O 3-2 + I 2--> I-+ S 4 O 6-2. check_circle Expert Answer. So far I have : I2 + e- → 2I but I can't figure out the part for the other compounds Acidic solution Balance: IO3^-+S2O3^2- -> I2 + S4O6^2-Expert Answer 100% (1 rating) Previous question Next question Get more help from Chegg.

S2O3^2-—→ S4O6^2- For such reaction we calculate the n factor for the atoms which show change in their oxidation states. They will make you ♥ Physics. So equivalent weight of iodine will be equal to molecular weight. To find the correct oxidation state of S in S2O3 2- (the Thiosulphate ion ion), and each element in the ion, we use a few rules and some simple math. Add your answer and earn points.
