Borax and boric acid are not the same thing, but there is a "relationship" between the two. Let's look at each and see the connection.


Borax is an important mineral, and it is goes under the names sodium borate, sodium tetraborate, or bisodium tetraborate. It's chemical formula will be written in basically one of two ways, depending on the water content. These formulae are:

Na2B4O7·10H2O and Na2[B4O5(OH)4]·8H2O

Boric acid

Boric acid has the chemical formula H3BO3, which is sometimes written B(OH)3 when referring to the naturally occurring mineral form of boric acid (sassolite). This weak acid will react to form a salt, and sodium borate (borax) is one of the salts that can result when boric acid reacts with other natural minerals, and that's the connection.

As borax can be a product of a boric acid reaction, we should not be surprised to find boric acid in borax, which we do. The fact that sodium borate is a product of a boric acid reaction and that boric acid can be found in borax (and several other minerals as well) connect the two substances.

What does borax and boric acid treatment do to cellulose fiber insulation?

The borax and boric acid treatment of cellulose fiber insulation discourages attack by insects. It's a stomach poison and it affects their metabolism while being largely innoc

How do you convert boric acid to boric oxide?

  Heat it. The boric acid will change into several different acids while bubbling the whole time. The bubbling action is the boric acid releasing the moisture from itself.

Is borax acid the same as table salt?

"No, although its toxicity is considered comparable." Boric acid is toxic. This is why it is no longer used for some of its prior uses. Please look at National Institutes of
