Redox titration formula
Web15. aug 2024 · Solution: (b) is a redox reaction since reaction involves electron transfer. Note that the oxidation state of Cu has moved from zero to +2, while that of Ag has changed from +1 to zero. Ag+ is the oxidizing agent (it gains an electron) while Cu is the reducing agent (it loses two electrons). WebIodine-Thiosulfate Titrations. A redox reaction occurs between iodine and thiosulfate ions: 2S2O32– (aq) + I2 (aq) → 2I–(aq) + S4O62– (aq) The light brown/yellow colour of the iodine turns paler as it is converted to colourless iodide ions. When the solution is a straw colour, starch is added to clarify the end point.
