What is the ionic strength of 0.01M barium chloride solution :
- A
0.03
- B
0.02
- C
0.04
- D
0.01
0.01: This option is correct. The ionic strength is equal to 0.01. In this case, the concentration of both the barium ions (Ba2+) and chloride ions (Cl-) is 0.01 M. Since there is only one ion of each type, the sum of their concentrations gives the total ionic strength of the solution, which is 0.01 M.
The ionic strength of a solution is a measure of the total concentration of ions in the solution. In this case, we have a 0.01 M barium chloride solution. To calculate the ionic strength, we need to consider the contribution of both the barium ions (Ba2+) and chloride ions (Cl-) to the total ionic concentration.
This option is not correct. The ionic strength is not equal to 0.03. It would be too high for a 0.01 M solution.
0.02: This option is not correct. The ionic strength is not equal to 0.02. It would be too high for a 0.01 M solution.
0.04: This option is not correct. The ionic strength is not equal to 0.04. It would be too high for a 0.01 M solution.
0.01: This option is correct. The ionic strength is equal to 0.01. In this case, the concentration of both the barium ions (Ba2+) and chloride ions (Cl-) is 0.01 M. Since there is only one ion of each type, the sum of their concentrations gives the total ionic strength of the solution, which is 0.01 M.
