0 Pa
Remarks on result:
other: Modified grain Method, estimated value from EPI Suite 4.11
Conclusions:

Description of key information

The result is calculated using EPI Suite.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

The experimental result emerged while using an instrument that was not able to measure below 10 Pa. Since the substance is a salt in an aqueous solution it was assumed the vapour pressure would be much below this and therefore a calculation was performed with EPI SuiteTM. This result is considered reliable and is used for further assessment.
