(a) The first redox reaction takes place in the flask before the titration: the OCl and the excess I produce I₃ and Cl in acidic solution. Balance this redox reaction using the half-reaction method as outlined in your lab manual (Expt. 3 Introduction). Reduce all coefficients to the smallest possible integers. All work must be shown on your Data and Observations Sheet in your Lab Manual prior to coming to your lab day.

Enter the correct coefficients in the boxes below. (Note that coefficients of "0" or "1", whenever required to balance the equation shown, must be entered here in the appropriate box(es), in order for this LON-CAPA problem to work. Normally one does not write equations this way. (see below)

(Eqn. 1) OCl + I + H⁺ I₃ + Cl + H₂O
