What is the Difference Between Borax and Boric Powder?

Borax and boric acid are distinct formulations of the same compound, boron, and share many similarities. Both are borates, compounds that come from the element boron. However, there are some differences between the two:

1. Chemical composition: Borax, also known as Sodium Tetraborate (Na₂B₄O₇*10H₂O), is made up of sodium, oxygen, and boron. Boric acid, on the other hand, is created from the mixture of borax with other naturally occurring minerals such as boracite and colemanite.
2. Form: Borax is mined in rock form and needs to be crushed or broken down to reach powder form. Boric acid is more powder-like and is produced as crystals.
3. Sodium content: Borax contains sodium, which can be a factor to consider if you want to add only boron to a substance. Boric acid does not contain sodium.
4. Concentration of boron: Boric acid has a slightly larger concentration of boron (17.48%) compared to borax (11.34%).
5. Molecular weight: The molecular weight of boric acid is 61.83, while borax has a much higher molecular weight of 381.43.
6. Solubility in water: Boric acid is more soluble in water than borax. Boric acid's solubility in water is 31.7 g/L, while borax's solubility is 2.52 g/100 mL at 0°C, 4.72 g/100 mL at 20°C, and 27.53 g/100 mL at 100°C.

Despite these differences, borax and boric acid have many overlapping uses and can be interchangeable in most applications. Both are known to be harmful to certain types of insects and have been used for centuries to achieve cleanliness. However, large amounts of either can be hazardous, so it is essential to use them in moderation and consult a doctor before ingesting either.

Comparative Table: Borax vs Boric Powder

Borax and boric powder are inorganic chemical compounds that contain the chemical element boron. The key difference between the two is that borax is a naturally occurring mineral, while boric powder is produced industrially from borax. Here is a comparison table highlighting the differences between borax and boric powder:

Both borax and boric powder are effective cleaners, disinfectants, deodorizers, and mold-killers.
