The ionic strength of a solution containing 0.008 M AlCl3 and 0.005 M ...
Calculation of Ionic Strength
Ionic strength is a measure of the total concentration of ions in a solution. It is calculated using the following formula:
Ionic Strength = 1/2 Σci zi2
Where,
ci = the molar concentration of each ion in the solution
zi = the charge of each ion
Given Information
The solution contains:
- 0.008 M AlCl3
- 0.005 M KCl
The charges of each ion can be determined from their chemical formulas:
- AlCl3 dissociates into Al3+ and 3Cl- ions
- KCl dissociates into K+ and Cl- ions
Therefore, the charges of each ion are:
- Al3+ = 3+
- Cl- = 1-
- K+ = 1+
Calculation
Using the formula for ionic strength and the given information, we can calculate the ionic strength of the solution as follows:
Ionic Strength = 1/2 [(0.008 M x (3+)2) + (0.008 M x 3 x 1-) + (0.005 M x (1+)2) + (0.005 M x 1 x 1-)]
Ionic Strength = 1/2 [(0.072) + (0.024) + (0.005) + (0.005)]
Ionic Strength = 0.053
Therefore, the ionic strength of the solution containing 0.008 M AlCl3 and 0.005 M KCl is 0.053. Rounded up to two decimal places, the answer is between 0.050 and 0.055, as given in the question.
