Temp.:

25 °C

Vapour pressure:

0 Pa

Remarks on result:

other: Modified grain Method, estimated value from EPI Suite 4.11

Conclusions:

Estimated value 3.52E-7 Pa at 25 °C (Modified Grain Method)

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 Suite^TM. This result is considered reliable and is used for further assessment.
