    All compounds dissolved in aqueous solution have a threshold concentration at which they are no longer soluble. When this concentration is exceeded, the molecules become supersaturated, at which point they begin to form insoluble crystals. Calcium oxalate, a soluble salt forming the most common type of kidney stones, becomes supersaturated at higher concentrations, forming stones that accumulate in the kidneys or urinary tract.[1]
