11. The solubility of two different substances in 100 g of water at different temperatures is given below. Substances Temperature/°C 283 293 313 333 Solubility
А 36 36 36 37
B 35 35 40 46
What mass of sample B would be needed to produce a saturated solution of B in 150g of water at 333K?
A. 469
B. 80g
C. 699
D. 599
Answers
Answer:
(a) At 313 K 62 g of potassium nitrate dissolved in 100 g of water. So to produce a saturated solution of potassium nitrate in 50 g of water we need
100
62
×50=31 g of potassium nitrate.
(b)Some soluble potassium chloride will separate out in the form of crystal at room temperature because the solubility of potassium chloride will decrease.
(c)
(i) Solubility of Potassium nitrate at 293 K is 32 g.
(ii) Solubility of sodium chloride at 293 K is 36 g.
(iii) Solubility of Potassium chloride at 293 K is 35 g.
(iv) Solubility of Ammonium chloride at 293 K is 37 g.
The solubility of Ammonium chloride is highest at this temperature.
(d)The solubility of salt increases with the increase in temperature.
