Quick answer: no, baking soda does not neutralize ammonia in litter. Both ammonia (NH₃) and baking soda are chemical bases—and a base does not neutralize another base. To truly eliminate ammonia, an acid-base reaction is needed, which transforms it into a harmless salt and water.
You may have already sprinkled baking soda at the bottom of your cat's litter box, as many guides and forums recommend. This is a logical step: baking soda is known to absorb odors in refrigerators or shoes. But against ammonia in litter, there's a chemistry problem that few articles clearly explain.
Ammonia is a base, not an acid
The pungent smell coming from the litter box comes from ammonia (NH₃), a compound released when bacteria break down urea in urine. Chemically, ammonia is a base: a molar solution of ammonia has a pH of approximately 11.6, which is distinctly alkaline.
Baking soda (sodium bicarbonate) is also a basic substance, with a pH of about 8.3 in solution. However, in chemistry, one base does not neutralize another base: the two compounds simply have no reason to react with each other. It's the chemical equivalent of pouring warm water into warm water hoping to cool it down.
What baking soda actually does
Baking soda is not useless in the litter box: it absorbs some ambient moisture and can slightly limit bacterial growth on the surface. But it does not act on the ammonia molecule itself. This is why the perceived effect is often temporary: the odor seems to be reduced for the first few hours, then returns as ammonia production continues—which is inevitable with each new cat visit.
What truly neutralizes ammonia: an acid-base reaction
To neutralize a base like ammonia, an acid is needed. This is a basic chemical reaction: an acid and a base react together to form a salt and water. For example, gaseous ammonia reacts with hydrochloric acid to form ammonium chloride, an inorganic salt soluble in water—a reaction documented and used for a long time in chemistry to treat ammonia vapors.
This is the principle on which CatDeo™ technology is based: upon contact with ammonia, it triggers a targeted acid-base reaction that converts the odor molecule into a harmless inorganic salt and water. Ammonia is not temporarily absorbed or masked by a fragrance: it is chemically transformed, irreversibly.
Why this distinction matters for your cat
A cat's nose is significantly more sensitive than ours. A product that masks odor with a fragrance adds an additional olfactory layer that the cat perceives as more intense, not more pleasant—which can, in some cases, discourage them from using their litter box. A solution that eliminates the molecule at the source, without added fragrance, respects the animal's sensory environment more. We detail this topic in this article.
In summary
- Litter ammonia is basic (pH ~11.6).
- Baking soda is also basic: two bases do not neutralize each other.
- Only an acid-base reaction targets the ammonia molecule to transform it into a harmless salt and water.
- CatDeo™ uses this chemical principle, without added fragrance, for a litter that truly no longer smells—not just masked.
