Question

how to calculate ionic strength of given solution of NaCl is the concentration of solution is 50 ml .

Answer 1

Use this formula to calculate ionic strength: I= 1/2 n∑i (CiZi )squared.


Let “n” represent the number of ions in solution. Since positive and negative ions can not separate, this needs to be considered as a factor in the equation.

Let “i” represent the specific ion in solution. "i" equal's 1.

Allow "Ci" to represent the concentration to the /th species, such as mole per liter.

Let “Zi“ represent the valence or oxidation number of the /th species. This is also known as the electrical charge of the ion.

Represent the summation of concentrations and valences of all ions by ∑ .
