is the answers correct?
a) What is the significance of the point of intersection between the KCI and KNO, curves in terms of their solubility? The point of intersection indicates that the two þurves have the same solubility temperature. b) Approximately how many grams of NaNO3 will dissolve in 100 g water at 10 °C? 80g NaNO3 c) How many grams of KCl will dissolve in 1 liter of H2O at 50 °C? 40g KCL/per 100g H20 d) 500 g of water are used to make a saturated solution of KCl at 15 °C. How many more grams of KCI could be dissolved if the temperature were raised to 78 °C? (50-30) *5=100g. e) A saturated solution of KNO3 in 200 g of H2O at 51 °C is cooled to 28 °C. How much KNO3 will precipitate out of solution? (72.5-40) *2= 65g.
