SUMMARY

The oxidation state of sulfur in the thiosulfate ion (S2O32-) is +2, as established in the discussion. In the reaction with chlorine (Cl2), one mole of S2O32- reduces four moles of Cl2, resulting in the release of 8 electrons. The oxidation state of chlorine in the resulting compound is -1, as each chlorine atom transitions from an oxidation state of 0 to -1 during the reduction process. The electronic balance must account for the conservation of chlorine atoms and the transfer of electrons.

PREREQUISITES
  • Understanding of oxidation states and electron transfer in redox reactions
  • Familiarity with thiosulfate ions (S2O32-) and their properties
  • Knowledge of balancing chemical equations
  • Basic principles of redox chemistry
NEXT STEPS
  • Study the principles of redox reactions and electron transfer mechanisms
  • Learn how to balance redox reactions using half-reaction methods
  • Explore the properties and reactions of thiosulfate ions in various chemical contexts
  • Investigate the role of chlorine in oxidation-reduction reactions
USEFUL FOR

Chemistry students, educators, and professionals involved in redox chemistry and reaction balancing will benefit from this discussion.

Homework Statement



One mole of aqueous S2O32- ions reduces four moles of Cl2 molecules. What is the oxidation state of the sulphur containing product of this reaction?

Homework Equations





The Attempt at a Solution



oxidation state in S2O32- = +2

since 4moles of Cl2 are reduced, 8 electrons are released by S2O32- ions.

these are all information i can get, but i have no ideas how to proceed, please help me..
 
Physics news on Phys.org
Write down the electronic balance and use the fact that the total nr of chlorine atoms should be conserved.

S_{2}O_{3}^{2-} + 4 Cl_2-----> ...

What's the oxydation state of chlorine in the resulting compound ? How many electrons are changes for all 8 ions ?

Thanks.. but i still don't understand..

I know that number of e- received by chlorine = number of e- released by S2O32-

but the problem is how i find the number of e- released by S2O32- from the information given?

Please guide me..:confused:
 
You should start with the chlorine. You know that 8 <pieces> of chlorine go from oxydation state 0 to oxydation state -1. How many electrons are captured ?
