How to interpret saturation index (SI) values for compounds in aqueous media if SI is
1. large negative
2. small negative
2. small positive (0-1), and
3. large positive (>1)?
SI tells us about the probability for a mineral to precipitate. Does it, somehow, also indicate the Solubilization of already precipitated mineral in a system?
If the SI for a compound is negative but very small (-0.149) can we still consider its probability of formation?
Please enrich me about the nitty gritties of saturation index.
