The quantity used to characterize aqueous solutions that contain different concentrations of ions is the ionic strength. The ionic strength is a measure of the magnitude ionic strength and increase as the concentration of ions increases.

The Ionic Strength Calculator calculates half of the total sum of the concentration of every ionic species.

## Steps for Ionic Strength Calculator

Step 1 :

Read the problem and identitfy the given values and form a table.

Step 2 :

Apply the ionic strength formula and subtitute the values to get the ionic strength value.

I = $\frac{1}{2} \sum Z^{2}C$

## Problems on Ionic Strength Calculator

1. ### Calculate the ionic strength of a 1 M KCl and 1 M CaCl2 solution.

Step 1 :

Form a table with the given values :

 Ions Z C Z2 K+ 1 1 1 Ca2+ 2 1 4 Cl- 1 3 1

Step 2 :

I = $\frac{1}{2}$ [ (1$\times$1) + (4$\times$1) + (1$\times$3)]

I = 4

The ionic strength of the given solution is 0.4

2. ### Calculate the ionic strength of an H3PO4 molar solution.

Step 1 :

Form a table with the given value.

 Ions Z C Z2 H+ 1 3 1 PO43- 3 1 9

Step 2 :

I = $\frac{1}{2}$ [3 $\times$ 1 + 1 $\times$ 9 ]

I = 6
