Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
The hydrolysis of carbonates is a well known chemical process. Hydrolysis of lithium carbonate produces basic solutions by generating lithium hydroxide and lithium hydrogen carbonate. The pH values can be calculated based on pKa values. The pH of a 0.02 mol solution is calculated to be 11.3. In water CO2 is the predominant species at a pH lower than 6.33, HCO3- (hydrogen carbonate ion) at a pH in the range of 6.35 - 10.33, and CO32- (carbonate ion) at a pH higher than 10.33. The carbonate will finally be incorporated into the inorganic and organic carbon cycle.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
