The solubility of KNO3 is 80g/100g water at 50 degrees and 10g/100g water at 0 degrees. The solubility of CuSO4 is 60g/100g water at 50 degrees and 20g/100g water at 0 degrees. A mixture contains 13.8g of KNO3 and 1.94g of CuSO4.
A 355g sample of a saturated solution of KNO3(s) in water is prepared at 25.0 degrees C. If 50g H2O is evaporated from the solution at the same time as the temperature is reduced from 25.0 to 0.0 degrees C, what mass of KNO3(s)
Hi, my question is: "Classify each of the following as saturated, supersaturated, or unsaturated: KNO3 90g/100g at 82*C NaCl 36g/100g at 23*C KCl 35g/100g at 18*C NaNO3 90g/100g at 28*C How do I determine if they are saturated,
