Applicant's summary and conclusion

Conclusions:
The physical state of arsenic acid is described both as a liquid and as a solid crystalline.
Executive summary:

The physical state of arsenic acid was found to be liquid (arsenic acid solution) and to be solid (arsenic acid hemihydrate).

The reliability of this result has been considered as 2 (reliable with restrictions) because 'CRC Handbook of Chemistry and Physics' is cited as a reference book containing peer reviewed data in the REACH Guidance Document R.7a.
