Worked example: Balancing a redox equation in acidic solution

WebAboutTranscript. When balancing equations for redox reactions occurring in acidic solution, it is often necessary to add H⁺ ions or the H⁺/H₂O pair to fully balance the equation. In this video, we'll walk through this process for the reaction between dichromate (Cr₂O₇²⁻) and chloride (Cl⁻) ions in acidic solution.. Created by Jay. WebBalance the equation H {+} + Cr2O7 {2-} + I {-} = Cr {3+} + I2 + H2O using the algebraic method. Label Each Compound With a Variable Label each compound (reactant or … WebError: equation can be balanced in an infinite number of ways: this is a combination of two different reactions.
