Key value for chemical safety assessment

Water solubility:
125 mg/L
at the temperature of:
25 °C

Additional information

According to reliable handbook data (e.g. CRC handbook and Merck Index) the water solubility of strontium sulfate is between 114 and 135 mg/L at 25°C. Handbook data considered to be from a trusted source acc. to "ECHA Guidance on information requirements and chemical safety assessment – Chapter R.7a: Endpoint specific guidance" and therefore, the water solubility of ~125 mg/L (moderately soluble) could be regarded as valid.
