# Preparation of Sodium Peroxoborate [closed]

Write balanced equations for each step, and an overall equation, for the preparation of sodium peroxoborate hexahydrate from the reagents borax, $$\ce{NaOH}$$, and $$\ce{H2O2}$$.

Borax was added to a solution of $$\ce{NaOH}$$, then it was treated with $$\ce{H2O2}$$, then cooled to form a precipitate. Please help.

(No structures are necessary, simply the chemical formulas will suffice)

2. Oxidation of sodium meta borate using $\ce{H2O2}$
If you can remove boric anhydride from the transparent glass like mixture, you can then add $\ce{H2O2}$
$$\ce{2NaBO2 + 2H2O2 + 6H2O -> Na2[(OH)2B(O - O)2B(OH)2].6H2O}$$
