Question

Laundry bleach such as Clorox is a dilute solition of sodium hypochlorite, NaOCl. Write a balanced net ionic equation for thr reaction of NaOCl woth Na2S2O3. The OCl- is reduced to chloride ion and the S2O3^2- is oxidized into a sulfate ion.

Answer 1

The balanced net ionic equation for the reaction of NaOCl with Na2S2O3 is as follows:

2 NaOCl + Na2S2O3 -> NaCl + Na2SO4 + 2 OCl-

In this reaction, NaOCl and Na2S2O3 react to form NaCl, Na2SO4, and OCl-. OCl- is reduced to chloride ion (Cl-), and S2O3^2- is oxidized into a sulfate ion (SO4^2-).
