NaCl is a compound that will dissociate into one Na- and one Cl+ ion in water. Because the Van't Hoff factor of an ionic compound is equivalent to the number of ions in the ionic formula, the Van't Hoff Factor is two.

Answer:

2 is the van’t Hoff factor for NaCl if it completely dissociates in water.

Explanation:

Formula used :

[tex]\alpha =\frac{i-1}{n-1}[/tex]

[tex]\alpha [/tex] = Degree of dissocation.

n = number of ions produced by dissociation of ionic compound

i = van't Hoff factor

We have:

[tex]NaCl(aq)\rightarrow Na^+(aq)+Cl^-(aq)[/tex]

n = 2. [tex]\alpha = 100\%=1[/tex]

[tex]1=\frac{i-1}{2-1}[/tex]

i = 2

2 is the van’t Hoff factor for NaCl if it completely dissociates in water.
