What is Ionic Strength?

Ionic Strength of a solution is a measure of the electrical intensity due to the presence of ions in the solution. It is given as half of the sum of all the terms obtained by multiplying the molality of each ion by the square of its valency. In other words, ionic strength is the cumulative measure of both charges on the ion as well as its concentration in the solution. The concept of ionic strength is always applicable to strong electrolytes (i.e salts) and it cannot be applied to weak electrolytes.
