plzz give me a thanks

Answer 2

Answer:

The ionic strength is equal to 4m.

Explanation:

Uni Bivalent electrolyte is $AB_2$ .

$AB_2 \longrightarrow A^2^+ + 2B^-$

$c_1 = m\\z_1=+2\\c_2 = 2m\\z_2 = -1$

I = (Σ$\frac{c_iz_1^2}{2}$)

$I = \frac{1}2}(m*(+2)^2) + 2*m *(-1^2))\\ I= \frac{1}{2} ( 4m +2m)\\ \\I=\frac{6m}{2} \\I = 3m$
