Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Type of information:
other: Handbook data
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
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". An identical figure of 30 µg/L as the water solubility of AgI is reported in three handbooks/databases: "CRC Handbook", "Merck Index" and "GESTIS".
no guideline followed
Principles of method if other than guideline:
Not applicable - Handbook/database information
Type of method:
other: no data
Water solubility:
30 µg/L
Remarks on result:
other: Temperature and ph are not reported in this handbook source.
silver iodide is insoluble (< 0.1 mg/L)

Description of key information

Multiple sources provide information indicating that the water solubility of silver iodide is low  (ca. 3 to 30 µg/L ). The highest figure of 30 µg/L, which is reported in three references, is used as the key value for the chemical safety asessement. 

Key value for chemical safety assessment

Water solubility:
30 µg/L
at the temperature of:
20 °C
