Formula Used in “Ionic Strength Calculator”
The ionic strength of a solution is calculated using the following standard formula:
I = 0.5 * Σ(ci * zi2)
Where:
Step-by-Step Breakdown of the Formula
- I = Ionic strength of the solution.
- ci = Concentration of each ion in the solution (in moles per liter, M).
- zi = Charge of each ion.
- The summation Σ indicates that you need to add together the products of each ion’s concentration and the square of its charge.
Example Calculation
Let’s take a real-world example to demonstrate how to use the ionic strength formula.
Scenario
Suppose you have a solution containing the following ions:
- Na+ with a concentration of 0.1 M
- Cl– with a concentration of 0.1 M
- Ca2+ with a concentration of 0.05 M
Input Table
| Ion | Concentration (M) | Charge (zi) | Concentration × Charge² |
|---|---|---|---|
| Na+ | 0.1 | +1 | 0.1 × (1)2 = 0.1 |
| Cl– | 0.1 | -1 | 0.1 × (–1)2 = 0.1 |
| Ca2+ | 0.05 | +2 | 0.05 × (2)2 = 0.2 |
Calculation
Using the ionic strength formula:
I = 0.5 * (0.1 + 0.1 + 0.2) = 0.5 * 0.4 = 0.2 M
Output
The ionic strength of this solution is 0.2 M.
