Question:medium

Consider the following redox reaction in basic medium. \( x\text{Cr(OH)}_3 + y(\text{IO}_3)^- + z(\text{OH})^- \rightarrow a(\text{CrO}_4)^{2-} + b(\text{I})^- + c(\text{H}_2\text{O}) \). The incorrect option about it is

Show Hint

When balancing redox reactions in a basic medium: 1. Balance atoms other than O and H. 2. Balance O atoms by adding \(H_2O\). 3. Balance H atoms by adding \(H^+\). 4. Balance charge by adding \(e^-\). 5. Add a number of \(OH^-\) ions to both sides equal to the number of \(H^+\) ions. 6. Combine \(H^+\) and \(OH^-\) to form \(H_2O\) and simplify the equation.
