What is the solubility of NaNO3 at 10 C?
At 10oC, 80 g of NaNO3 will dissolve in 100 mL (a saturated solution) • Say we only needed 60 mL of a NaNO3 solution. Other Useful Information: Solutes whose curves move upward with increased temperature are typically solids because the solubility of solids increases with increased temperature.
