We have three aqueous solutions of NaCl labelled as A, B and C with concentration `0.1 M , 0.01 "and" 0.001` M , respectively . The value of van't Hoff factor for these solutions will be in the order :

Options

A. `i_A lt i_B lt i_C`
B. `i_A gt i_B gt i_C`
C. `i_A=i_B =i_C`
D. `i_A gt i_B lt i_C`

Answer

C

Explanation

As NaCl is a strong electrolyte , it undergoes dissociation completely . Thus, van't Hoff factor will be same for all these solutions , `i_A=i_B=i_C`
