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

Answer:

[Ca (2+) ] = 0.15M

[Cl (-) ] = 0.30 M
