## Ionic strength of uni-bivalent electrolyte Solution

STEP 0: Pre-Calculation Summary
Formula Used
ionic_strength = (1/2)*(Molality of cation*((Valencies of cation)^2)+(2*Molality of anion*((Valencies of anion)^2)))
I = (1/2)*(m+*((Z+)^2)+(2*m-*((Z-)^2)))
This formula uses 4 Variables
Variables Used
Molality of cation - The molality of cation is defined as the number of moles of cation per kg of the solvent. (Measured in Mole per Kilogram)
Valencies of cation- The Valencies of cation are the positive charge of the ion in an electrolyte.
Molality of anion - The Molality of anion is defined as the number of moles of anion per kg of solvent. (Measured in Mole per Kilogram)
Valencies of anion- The Valencies of anion are the negative charge of the ion in an electrolyte.
STEP 1: Convert Input(s) to Base Unit
Molality of cation: 0.1 Mole per Kilogram --> 0.1 Mole per Kilogram No Conversion Required
Valencies of cation: 1 --> No Conversion Required
Molality of anion: 0.2 Mole per Kilogram --> 0.2 Mole per Kilogram No Conversion Required
Valencies of anion: 1 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
I = (1/2)*(m+*((Z+)^2)+(2*m-*((Z-)^2))) --> (1/2)*(0.1*((1)^2)+(2*0.2*((1)^2)))
Evaluating ... ...
I = 0.25
STEP 3: Convert Result to Output's Unit
0.25 Mole per Kilogram --> No Conversion Required
0.25 Mole per Kilogram <-- Ionic strength

## 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.

## How to Calculate Ionic strength of uni-bivalent electrolyte?
