A) KCl, 50% ionised
B) \[{{K}_{2}}S{{O}_{4}},\]40% ionized
C) \[FeC{{l}_{3}},\]30% ionized
D) \[SnC{{l}_{4}},\]20% ionised
Correct Answer: C
Solution :
| solute | y | x | \[i=[1+(y-1)x]\] | |
| [a] | KCl | 2 | 0.5 | 1.5 |
| [b] | \[{{K}_{2}}S{{O}_{4}}\] | 3 | 0.4 | 1.8 |
| [c] | \[FeC{{l}_{3}}\] | 4 | 0.3 | 1.9 |
| [d] | \[SnC{{l}_{4}}\] | 5 | 0.2 | 1.8 |
