For a particular redox reaction, bro− is oxidized to bro−3 and fe3 is reduced to fe2. complete and balance the equation for this reaction in basic solution. the phases are optional

Respuesta :

The balanced chemical equation in a basic solution will be,

[tex]BrO^{-} + 4OH^{-} +4Fe^{+3}[/tex] → [tex]BrO_{3} ^{-} + 4H_{2} O+4Fe^{+2}[/tex]

The reaction in which oxidation and reduction reaction takes place simultaneously is called redox reaction or oxidation - reduction reaction .

Rules for the balanced chemical equation in a basic solution are :

  • First write half - reaction.
  • Now balancing the main atoms in the reaction
  • Now balancing the hydrogen and oxygen atoms on both sides of the reaction .
  • If the oxygen atoms is not balance on both side then add water molecule at that side at that side where more number of oxygen atom is present.
  • If the hydrogen atom are not balanced on both side then add hydroxide ion at that side of where less number  of hydrogen are present.
  • Now at last balance the charge.

Therefore, the balanced chemical equation in a basic solution will be,

[tex]BrO^{-} + 4OH^{-} +4Fe^{+3}[/tex] → [tex]BrO_{3} ^{-} + 4H_{2} O+4Fe^{+2}[/tex]
