A student watched what happened when sodium chloride and sodium iodide were reacted one at a time with concentrated sulfuric acid and with concentrated phosphoric acid. Some of the observations are shown in the table. Which deduction can be made from these observations?
- AConcentrated phosphoric acid is a stronger oxidising agent than concentrated sulfuric acid.
- BConcentrated phosphoric acid is a stronger oxidising agent than iodine.
- CConcentrated sulfuric acid is a stronger oxidising agent than chlorine.
- DConcentrated sulfuric acid is a stronger oxidising agent than iodine.
