- a preferred dissolution rate for balls is 5 to 10 minutes (depending on the water temperature) and the proportion of salt for carbonate release.
- Also part of the invention is the use of a disulfite salt to improve the storage stability of a solid comprising a carbonate salt or a powder mixture comprising a carbonate salt which is suitable for releasing CO 2 upon contact with liquid water.
