Explain how the addition of HCO3- can push the reaction forward in the context of the given chemical equation and explanation?
Explain how the addition of HCO3- can push the reaction forward in the context of the given chemical equation and explanation?
The addition of HCO3- removes H+ ions, which lowers the potential of the AsO43-/AsO33- system, allowing arsenite to be oxidized quantitatively by iodine.
How can the presence of excess I2 push the reaction forward in the Fe3+/ Fe2+ system?
How can the presence of excess I2 push the reaction forward in the Fe3+/ Fe2+ system?
Excess I2 lowers the oxidation potential of the I2/I- system, allowing I- to be oxidized quantitatively into iodine.
Explain how the addition of F- or phosphate can push the reaction backward in the I2/2I- system & Cu2+/Cu+ system?
Explain how the addition of F- or phosphate can push the reaction backward in the I2/2I- system & Cu2+/Cu+ system?
The addition of F- or phosphate forms complexes with Fe3+, lowering the oxidation potential of the I2/2I- system, which pushes the reaction backward.
