Question

How should you label a 5.0 ppm SrCl2 solution in units of ppm Cl-?

Answer 1

SrCl_​​​2 is a strong electrolytes which dissociates completely

SrCl_​​​2 ---------> Sr^{​​​​​2+} +2Cl^1-

So if we have 5.0ppm concentration of SrCl_​​​2 it means it give double of Cl^{​​​​​-} ions.

The concentration of solution in the form of chloride ions is 10ppm
