For most ionic compounds, there is also a limit to the amount of compound can be dissolved in a sample of water. For example, you can dissolve a maximum of 36.0 g of NaCl in 100 g of water at room temperature, but you can dissolve only 0.00019 g of AgCl in 100 g of water. We consider NaCl soluble but AgCl insoluble.Potassium nitrate is extremely soluble in water. The solubility of potassium nitrate is 60 g KNO3 per 100 g of water at 42oC. 1. If 35 g of KNO3 is dissolved in 100 g of water at the same temperature, would the solution be saturated or unsaturated?
