Question

At 283 K, a saturated solution of solid X can be prepared by dissolving 21.0 g
of it in 100 g of water. The maximum amount of X which can be dissolved in
100 g of water at 313 K is 62.0 g. An attempt is made to dissolve 50.0 g of X in
100 g of water at 313 K.
i. All the 50.0 g of X will dissolve at 313 K
ii. At 313 K, 29.0 g of X will remain undissolved
iii. The solubility of X decreases with an increase in temperature
iv. On cooling the solution of X from 313 K to 283 K more than 21.0 g of X will
crystallize out.
