Basic Chrome Sulfate - Chromotel XGS - 25kg
Chromotel XGS
This basic chrome sulfate is sourced from NOVACHROM (Russia)
Basic chromium sulfate is produced from chromate salts by reduction with sulfur dioxide, although other methods exist.The reduction could formally be written:
Na2Cr2O7 + 3 SO2 + H2O → Cr2(SO4)3 + 2NaOH
Since 33% of the anion charges are due to hydroxy ions the basicity is 33% (but in tanning jargon it is known as 33% reduced).
