Question

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

Answer 1

The balanced chemical equation in a basic solution will be,

$BrO^{-} + 4OH^{-} +4Fe^{+3}$ → $BrO_{3} ^{-} + 4H_{2} O+4Fe^{+2}$

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,

$BrO^{-} + 4OH^{-} +4Fe^{+3}$ → $BrO_{3} ^{-} + 4H_{2} O+4Fe^{+2}$
