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)lti_(B)lti_(C)`
B. `i_(A)gti_(B)gti_(C)`
C. `i_(A)=i_(B)=i_(C)`
D. `i_(A)lti_(B)gti_(C)`

Answer

B

Explanation

van't Hoff factor is the measurement of total number of ions present in the solution. Therefore greater the concentrationof solution greater will be its van't Hoff factor.
