At 30°C approximately 10g of KCIO3 will dissolve in 100g of water.

#### What is the solubility of potassium chloride at 10 C?

At 10 ∘C , the solubility of potassium chloride is measured to be 31.2⋅g per 100⋅g of water.

**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.
