Procedure

Due to the presence of [NaHSO4] and hydrobromic acid (hydrogen bromide) [HBr], along with a decrease in pH down to about 1, the acidity of the chemically treated aqueous phase was neutralized using the 34-35 weight percent aqueous solution of sodium hydroxide. The [NaHSO4] and hydrobromic acid [HBr] present in the chemically treated aqueous phase reacted with the sodium hydroxide to form [NaBr], [Na2SO3], and [Na2SO4], in the resulting neutralized chemically treated aqueous phase, along with increasing the pH thereof to a value in a range of between about 7 and about 12.
