Calculate the concentration of all ions present in the solution of strong electrolytes 0.15 m calcium chloride

Calcium chloride, Ca Cl2 is a strong electrolyte which means that if fully ionizes. This is the ionization equation:

CaCl2 ---> Ca(2+) + 2 Cl(-).

So, per each mole of CaCl2 1 mole of Ca(2+) and 2 moles of Cl(-) are produced.

That means that the concentration of Ca(2+) is the same concentration of CaCl2 and the concentration of Cl(-) is twice the concentration of CaCl2.

=> [Ca(2+)] = 0.15 M, and [Cl-] = 2 * 0.15M = 0.30M

[Ca(2+)] = 0.15M

[Cl(-)] = 0.30 M

The correct answer is b.hoped i you

about what?
have a good day
