In this brief guide, we will answer the question, “does baking soda neutralize bleach?” and discuss what are some other ways to neutralize the bleach.

Does baking soda neutralize bleach?

Yes, baking soda neutralizes the bleach.

Chemical productChemical name in ChemistryChemical formula
Baking sodaSodium bicarbonateNaHCOΛ3
BleachSodium hypochloriteNaClO

The chemical reaction between baking soda and bleach results in neutralization.

The hypochlorite ion ClO- is formed by bleach which acts as a conjugate base with the formation of a weak acid which is hypochlorous acid HClO.

Whereas 

The hydrogen carbonate ion HCOΛ3- is formed by baking soda which acts as a conjugate acid with the formation of a weak base which is carbonate CO3Λ2-.

Thus, the overall neutralization reaction is as follows:

Hydrogen carbonate ion (HCOΛ3-) + Hypochlorite ion (ClO)⟶ Carbonate (CO3Λ2-) + Hypochlorous acid (HClO)

Some other ways to neutralize bleach

  • Use of hydrogen peroxide and water in a ratio of 1:10 (hydrogen peroxide to water ratio)
  • Use of sodium thiosulfate as a neutralizer
  • Bisulfite as a neutralizer

Conclusion

In this brief guide, we have addressed the question, “does baking soda neutralize bleach?” and discussed other questions related to the subject, such as what are some other ways to neutralize the bleach.
