Conclusions:
The water solubilitydetermination of test item Hydroxylamine-O-sulphonic acid;CAS No.2950-43-8 was doneby spectrophotometric method. The water solubility was determine to be 134500 mg/L at 25°C.
Executive summary:

The water solubility determination of test item Hydroxylamine-O-sulphonic acid (CAS No. 2950-43-8) was done as per the

OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of (Hydroxylamine-Osulphonic

acid of CAS No.2950 -43 -8 )in water was determine to be 134500 mg/L at 25°C. Thus it is concluded that chemcial is very soluble in water.
