The key difference between borax and baking soda is that the borax is a sodium borate that appears as a white solid whereas the baking soda is a sodium bicarbonate that appears as white crystals.
Borax is a term that describes a class of chemical compounds that include hydrated and anhydrous sodium borate. Moreover, it is a salt of boric acid, which is a common ingredient in many detergents, cosmetics and enamel glazes. Baking soda is sodium bicarbonate, which has many uses including cooking, pest control, medical uses, as a cleaning agent, etc. Let us discuss more details on these compound as follows.

What is Borax?
Borax is a common name for either anhydrous or hydrated forms of sodium borate. It is a salt of boric acid. The general chemical formula of this compound is Na2B4O7·10H2O because the name borax is usually used for the decahydrate form of sodium borate. It appears as a white solid. The molar mass of this compound is 381.38 g/mol. This compound easily converts into boric acid.
Na2B4O7·10H2O + 2 HCl → 4 H3BO3 + 2 NaCl + 5 H2O
Moreover, we can use this compound (decahydrate form) as a primary standard for titrimetric analysis. That is because this compound is sufficiently stable and pure for that purpose. Borax naturally occurs in evaporite deposits produced by the repeated evaporation of seasonal lakes.

The uses of this compound include followings;
- As an ingredient in laundry products and cleaning agents
- To make buffers
- To form complexes with various other substances
- For water-softening
- For the extraction of gold in small-scale gold mining
What is Baking Soda?
Baking soda is sodium bicarbonate. It is an inorganic solid compound that appears as white crystals. It has the chemical formula NaHCO3, and the molar mass is 84 g/mol. Moreover, it is a salt containing sodium cations and bicarbonate anions. The naturally occurring form of this compound is “nahcolite”.

The major uses of this compound are as follows:
- We can use this compound for cooking purposes as a leavening agent
- As a pest control to kill cockroaches
- It can raise the alkalinity of water sources
- Useful as a mild disinfectant
- Useful for the neutralization of acids and bases
What is the Difference Between Borax and Baking Soda?
Borax is a common name for either anhydrous or hydrated forms of sodium borate. The general chemical formula of borax is Na2B4O7·10H2O. It has the molar mass 381.38 g/mol. Moreover, it is useful as a cleaning agent, to make buffers, for water-softening, for small-scale gold extractions, etc. Baking soda is sodium bicarbonate. The chemical formula of this compound is NaHCO3. Its molar mass is 84 g/mol. More importantly, it is useful as a leavening agent in cooking, a pest control, to raise alkalinity, as a mild disinfectant, etc. These are the important differences between borax and baking soda.
Summary – Borax vs Baking Soda
Both borax and baking soda are common names of two different chemical compounds. The difference between borax and baking soda is that the borax is a sodium borate that appears as a white solid whereas the baking soda is a sodium bicarbonate that appears as white crystals.
