Calcium citrate also a relatively low solubility (~15 mM in the cold), and its solubility decreases as the temperature goes up. Thus, getting calcium citrate crystals is a possibility if both components are at a relatively high concentration. However, sodium citrate alone is soluble up to ~1.4 M at least, depending on the pH. | Calcium citrate also a relatively low solubility (~15 mM in the cold), and its solubility decreases as the temperature goes up.

A list of conditions from commercial screens, where people obtained crystals that turned out to be from salt, is at [[Conditions prone to salt crystallization]]. This should not be taken to mean that these conditions ''always'' produce salt crystals, but they apparently sometimes do. | |||
