Undersaturation

{{Short description|State of solution}}

Undersaturation is a state of a solution that contains less of a dissolved material than could be dissolved by that quantity of solvent under normal circumstances. It can also refer to a vapor of a compound that has a lower (partial) pressure than the compound's vapor pressure. Undersaturation is often followed by ingassing of the solvate until saturation is reached.{{cite web|url=https://www.science.org/doi/abs/10.1126/science.1174190|title=Aragonite Undersaturation in the Arctic Ocean: Effects of Ocean Acidification and Sea Ice Melt|publisher=sciencemag.org|access-date=2014-08-08}}{{cite web|url=http://environmentalresearchweb.org/cws/article/news/41070|title=Arctic Ocean undersaturated for calcium carbonate - environmentalresearchweb|publisher=environmentalresearchweb.org|access-date=2014-08-08}}{{cite journal|title=Aragonite undersaturation in the Arctic Ocean: effects of ocean acidification and sea ice melt| pmid=19965425 | doi=10.1126/science.1174190 | volume=326| issue=5956 | journal=Science| pages=1098–100 | last1 = Yamamoto-Kawai | first1 = M | last2 = McLaughlin | first2 = FA | last3 = Carmack | first3 = EC | last4 = Nishino | first4 = S | last5 = Shimada | first5 = K| bibcode=2009Sci...326.1098Y | year=2009 }} Most states of solution involve undersaturation.
