Sodium Hydrosulfite bleach (Na 2S 2O 4) is produced by adding BOROL SOLUTION to a mixture of aqueous NaOH and liquid/aqueous sulfur dioxide (SO 2). As an alternative, BOROL can be added to an aqueous solution of Sodium Bisulfite (NaHSO 3). NaBH 4 + NaOH + SO 2 → Na 2 S 2 O 4 NaBH 4 + NaHSO 3 → Na 2 S 2 O 4
