Which of the following solutions of strong electrolytes contain the largest number of ions:

Question

100.0 mL of 0.30 M AlCl3,
50.0 mL of 0.60 M MgCl2,
200.0 mL of 0.40 M NaCl?

Answer 1

If you determine the volumes of these three ionic compounds, NaCl has the greatest volume.

AlCl3--Has four ions
MgCl2--has 3
NaCl-has 2

Salt can hold more Na+ to Cl- collisions. which form ionic compounds since there is a greater volume.
