Question

Q3). Pragya tested the solubility of three different substances al
(results are given in the following table, as grams of substance
different temperatures and collected the data as given below
dissolved in 100 grams of water to form a saturated solution).

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