Baking Soda is a White Crystalline Powder also Known as Sodium Bicarbonate, which Acts as a Buffer to Neutralize Odor.

  • When added to acid solutions, a buffer raises their pH.
  • When added to alkaline solutions, it lowers their pH.
  • It always tries to bring whatever solution it is in to its own pH.
  • Baking soda has a pH of 8 which is slightly alkaline.

Most Odors Come from Either Strong Acids Like Sour Milk or Strong Bases Like Spoiled Fish.

  • Food odors resulting from either acidic or basic compounds can be neutralized with baking soda into more neutral and odor-free salts.
  • Baking Soda can also deodorize when it’s dissolved in water.
