Question

Pragya tested the solubility of four different substances at different temperatures and collected the data as given below (results are given in the following table, as grams of a substance dissolved in 100 grams of water to form a saturated solution).
SOLUBILITIES OF VARIOUS SALTS AT DIFFERENT TEMPERATURES
temperatures and collected the data as given below (results are given

SOLUBILITIES OF VARIOUS SALTS AT DIFFERENT TEMPERATURES
Substance Dissolved 283K 293K 313K 333K 353K
Potassium nitrate 21 32 62 106 167
Sodium chloride 36 36 36 37 37
Potassium chloride 35 35 40 46 54
Ammonium chloride 24 37 41 55 66

ANSWER THE FOLLOWING – BASED ON THE TABLE

(a) What mass of potassium nitrate would be needed to produce a saturated

a solution of potassium nitrate in 50 grams of water at 313 K?

(b) Pragya makes a saturated solution of potassium chloride in water at 353 K

and leaves the solution to cool at room temperature. What would she

observe as the solution cools? Explain.


(c) Find the solubility of each salt at 293 K. Which salt has the highest

solubility at this temperature?

(d) What is the effect of change of temperature on the solubility of a salt?
