Calculate the standard cell emf for the reaction: clo3−(aq)+3cu(s)+6h+(aq)→cl−(aq)+3c u2+(aq)+3h2o(l) pt is used as an inert electrode in contact with the clo3− and cl−. calculate the standard emf using data in appendix e and given the following: clo3−(aq)+6h+(aq)+6e−→cl−(aq)+3h2o( l); e∘=1.45 v express the emf to three significant figures with the appropriate units. v

The standard EMF of the cell is 1.11 V

Explanation:

For the given chemical equation:

The half reaction follows:

Oxidation half reaction:      ( × 3)

Reduction half reaction:

To calculate the of the reaction, we use the equation:

Substance getting oxidized always act as anode and the one getting reduced always act as cathode.

Calculating the using above equation, we get:

Hence, the standard EMF of the cell is 1.11 V

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots
