sodium percarbonate to sodium carbonate

[chilsaoui]

hi all

i searched sodium carbonate everywhere but haven't found it but i found sodium percarbonate

can you tell me how to produce sodium carbonate (Na2CO3) from sodium percarbonate (2Na₂CO₃·3H₂O₂₎

_{i have read in wikipedia that sodium percarbonate under water is decompossed to sodium carbonate and hydrogene peroxyde}

_{if that is true how to separe sodium carbonate from this solution}

thanks

Try the supermarket for soda. The normal one, not the caustic. It should come as a white, crystalline powder.

It would seem strange tome that you can't find washing soda for sale.

Another option to look for would be baking soda (sodium bicarbonate)

However, if you want, you can convert the percarbonate to the carbonate by heating it.
