Question

Chlorine dioxide (ClO₂), which is produced by the reaction below, has been tested as a disinfectant for municipal water treatment.

2 NaClO₂(aq) + Cl₂(g) → 2 ClO₂(g) + 2 NaCl(aq)

(a) Using data from the Standard Reduction Potentials table, calculate ℰ°, ΔG°, and K at 25°C for the production of ClO₂.

ℰ°		V
ΔG°		kJ
K

(b) One of the concerns in using ClO₂ as a disinfectant is that the carcinogenic chlorate ion (ClO₃⁻ ) might be a by-product. It can be formed from the following reaction.

ClO₂(g) → ClO₃⁻(aq) + Cl⁻(aq)

Balance the equation for the decomposition of ClO₂. (Use the lowest possible coefficients. Include states-of-matter at 25°C and 1 atm in your answer.)

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
