WebSodium tetraborate (Na 2 B 4 O 7) can be used as a co-catalyst for the oxidation of alcohols to corresponding carbonyl compounds in greener non-chlorinated solvents in the presence of TEMPO/NaOCl. It is also used as a structure-directing agent as well as a catalyst in the preparation of carbon aerogels using glucose as the carbon precursor. WebBoric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula B(OH) 3.It may also be called hydrogen orthoborate, trihydroxidoboron or boracic acid. It is usually encountered as colorless crystals or a white powder, that dissolves in water, and occurs in nature as the mineral sassolite.It is a weak …

WebBorate buffer System Background There are various procedures for making a borate buffer. One method is to prepare a working buffer by using H 3 BO 3 and NaOH, or by using sodium tetraborate and HCl. Perhaps the most elegant method is to use sodium tetraborate also known as borax (Na 2 B 4 O 7 ·10H 2 O) and H 3 BO 3. The boric acid-borate ... WebAlso make a solution of Boric acid (H3BO3).
