← ScienceWhich outcome will result when molecular iodine concentration increases significantly in aqueous solution?
A)Increased triiodide ion concentration predominates✓
B)Increased hydroxide radical formation occurs
C)Molecular iodine precipitates immediately out
D)Deionized water resists conductivity weakly
💡 Explanation
The triiodide ion concentration increases because of increased molecular iodine resulting in **complex formation**. Iodine molecules react with iodide ions already in solution to form triiodide ions; therefore, higher iodine concentration shifts the equilibrium toward excess triiodide, rather than precipitation or radical formation.
