Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): miscible
Sulphuric acid is miscible to water.
Executive summary:

Water solubility of the UVCB can be read-across from its major constituent Sulphuric acid (which is miscible in water). The behaviour of the minor constituents of the substance can be derived from solubility of the respective sulphate salts (eg copper sulphate, iron sulphate, aluminium sulphate, etc), as totally dissolved in the UVCB.
