20 pointsthe solubility of pottasium nitrate is 32g/100g of water at 20°c and 62g/100g of water at 40°c. what will you observe if a saturated solution of pottasium nitrate at 400c is cooled to 20°c.

When solution will be cool down, the some potassium nitrate should precipitate, because water at 20⁰ C, can hold less  potassium nitrate than water at 40⁰C.

62-32=30 g of  potassium nitrate will be precipitating of solution that contains  100 g of water.
