Question

At a given temperature 54g if a substance dissolves in 150g of water to produce a situated solutions. Calculate the solubility of the substance at that temperature

Answer 1

Answer:

Explanation:

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.

(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.
