For part a, b, state whether each of the following solutions is saturated, unsaturated, or supersaturated. (a) 80 g Sodium Nitrate in 50 g H2O at 10ºC
(b) 30 g Ammonium Chloride in 200 g H2O at 10ºC
(c)According to Reference Table G, how many grams of potassium nitrate would be needed to saturate 50 grams of water at 70ºC?
(d)Tell how many grams of potassium nitrate is ill crystallize/precipitate/settle when the solution of potassium nitrate is cooled from 70ºC to 40ºC. Assume all solutions are saturated and in 100 grams of H2O.
