c. write the equation in ionic form

Explanation:

  • Using the half equation or half cell method, one can balance ionic redox equations representing redox reactions occuring in acid or basic/neutral medium.
  • Split the equations into two halves with one representing the oxidation reaction and the other reduction reaction.
  • By inspection balance each of the half equations with respect to atoms and charges.
  • Multiply each half equations with appropriate factors to balance the number of electrons in the two half equations.
  • Add up the two balanced halves and cancel out species that appear on both sides in the combined equation.
  • If needed, divide or multiply each of the coefficient in the combined equation by a factor to avoid fractions and express in simple terms.
  • Check to ensure the balance of atoms and charges.
