Question

Bactericide and Virucide The water-soluble gas ClO2 is known as an oxidative biocide. It destroys bacteria by oxidizing their cell walls and destroys viruses by attacking their viral envelopes. ClO2 may be prepared for use as a decontaminating agent from several different starting materials in slightly acidic solutions. Complete and balance the following chemical equations for the synthesis of ClO2.

A. ClO3−(aq) + SO2(g) → ClO2(g) + SO42−(aq)

B. ClO3−(aq) + Cl−(aq) → ClO2(g) + Cl2(g)

C. ClO3−(aq) + Cl2(g) → ClO2(g) + O2(g)
