Question
Transcribed Image Text:In a particular redox reaction, Cr is oxidized to CrO2- and Fe³+is reduced to Fe² +. Complete and balance the equation for this
reaction in acidic solution. Phases are optional.
balanced redox reaction: 80H¯ + Cr + 6Fe³+
Incorrect
CrO²¯ +6Fe²+ + 4H₂O
Expert Solution
Step 1
Redox reactions can be balanced easily by following steps:
1. Identify the oxidation and reduction half-reactions and write them separately.
2) Balance all atoms other than oxygen and hydrogen.
3) Balance oxygen atoms using water molecules.
4) Balance hydrogen atoms using hydrogen ions.
5) If the medium is basic, neutralize the hydrogen ions using hydroxyl ions.
6) Then balance the charges using electrons.
7) Add the two half-reactions such that the number of electrons on either side is equal.
