Question

We have three aqueous solutions of NaCl labelled as ‘A’, ‘B’ and ‘C’ with concentration 0.1 M, 0.01M & 0.001 M, respectively. The value of van t’ Haft factor (i) for these solutions will be in the order. (A) iA < iB < iC (B) iA < iC < iB (C) iA = iB = iC (D) iA > iB > iC

Prashant Kotian · Accepted Answer

Correct answer: A. Salt Values of i (for different conc. of a Salt) 0.1 M 0.01 M 0.001 M NaCl 1.87 1.94 1.94 i approach 2 as the solution become very dilute.
