In order to apply a solubility curve to determine whether a solution is saturated or unsaturated,each substancethat is referenced in the given problem must first be classified as a solute or a solvent. A. So, you've learned about dissolution and how a solution forms. A saturated solution of potassium chlorate is dissolved in 100 g of water. KNO3 is a highly ionic compound that dissolves easily in water (a highly polar solvent) to form potassium cations and nitrate anions that are solubilized by water molecules (for potassium, partially negatively charged oxygen atoms from water molecules stabilize the ion in aqueous solution while for nitrate, the partially negatively charged oxygen atoms from water molecules stabilize it in aqueous solution). calculate the amount of excess solute that remains undissolved inthe resultant solution. Solubility varies according to temperature for the same solute and solvent. [ At 90 degrees, 145 grams can be dissolved, at 45 degrees, only 12ish grams.
