Question

the vant hoff's factor for an aqueous solution of an electrolyte is​

Answer 1

Greater than 1

Explanation:

The van't Hoff factor for an electrolyte is greater than 1.

For example, consider NaCl which is a strong electrolyte and completely dissociates.

$NaCl \: →Na^+ + Cl^-$

Thus, 1 mole of NaCl on dissociation gives 2 moles of ions.

Hence, the van't Hoff factor i=

Number of particles for no ionization/

Actual number of particles

= 2/1

=2.
