From Cr₂O₇²⁻ + 6S₂O₃²⁻ + 14H → 2Cr₃ + 3S₄O₆²⁻ + 7H₂O subjected to reduced reaction is Cr₂O₇²⁻.
Reduction is a reaction that undergoes a decrease in the oxidation state and an increase in electrons. It can be said that reduction is a reaction by which a substance loses oxygen.
In this problem reaction, the reaction that releases oxygen is:
Cr₂O₇²⁻ → 2Cr₃ (Reduction: releasing oxygen)
An oxidation reaction is a reaction that experiences an increase in the oxidation state and a decrease in electrons. It can be said that oxidation is a reaction by which a substance binds oxygen.
In this problem reaction, the reaction that binds oxygen is:
14H → 7H₂O (Oxidation: binds oxygen)
