Direction: Q. 6 to 10 | |||||
Read the following and answer questions from [6] to [10]. | |||||
Abhinav tested the solubility of four different salts, i.e. potassium nitrate, sodium chloride, potassium chloride and ammonium chloride at different temperature. | |||||
He took four beakers and marked as (I) Potassium nitrate, (II) Sodium chloride, (III) Potassium chloride, (IV) Ammonium chloride and then he dissolved each salt in 100 g of water and placed a thermometer in it. Heated the contents of the beaker and recorded the following observations. | |||||

I. Potassium nitrate | 21 | 32 | 62 | 106 | 167 |
II. Sodium chloride | 36 | 36 | 36 | 37 | 37 |
III. Potassium chloride | 35 | 35 | 40 | 46 | 54 |
IV. Ammonium chloride | 24 | 37 | 41 | 55 | 66 |
A) I
B) III
C) IV
D) II
Correct Answer: D
Solution :
[d] Solubility is the maximum amount of solute (in g) dissolved in a solvent. Sodium chloride have highest solubility (36 g) at 283 K.You need to login to perform this action.
