Use the half reaction method to balance the following equations in acidic solution. Identify the oxidizing and reducing agents b. SeO₃²- + I⁻ = Se + I₂
a) SeO₃²- + 2I⁻ + 6H⁺ = Se + 3I₂ + 3H₂O; SeO₃²- is oxidizing agent, I⁻ is reducing agent
b) SeO₃²- + 6I⁻ + 9H⁺ = Se + 3I₂ + 6H₂O; SeO₃²- is reducing agent, I⁻ is oxidizing agent
c) SeO₃²- + 3I⁻ + 6H⁺ = Se + I₂ + 3H₂O; SeO₃²- is reducing agent, I⁻ is oxidizing agent
d) SeO₃²- + 4I⁻ + 6H⁺ = Se + 2I₂ + 3H₂O; SeO₃²- is oxidizing agent, I⁻ is reducing agent
