When 1.00 mol of each compound below is dissolved in enough water to yield a 10.0 L solution, which solution contains the greatest concentration of ions?
The solution that holds the greatest concentration of ions is A.
There are 3.00 mol/L of ions present.
While the second step is not completed, the first one is.
Let's assume for the purposes of argument that the ion concentration is 2.1 mol/L.
Let's assume for the purposes of argument that the ion concentration is 0.5 mol/L.
Compared to phosphoric acid, it is weaker.
The concentration of ions is 0.05 mol/L because 1 mol of acetic acid may contribute 0.05 mol of ions.

The solution containing the greatest concentration of ions would be the one with the highest number of ions per mole of solute. To determine this, we need to calculate the number of ions produced by each compound when dissolved in water.
-
NaCl (sodium chloride) dissociates into 2 ions (Na⁺ and Cl⁻) per formula unit. Number of ions = 2 ions/mol
-
MgCl₂ (magnesium chloride) dissociates into 3 ions (Mg²⁺ and 2Cl⁻) per formula unit. Number of ions = 3 ions/mol
-
AlCl₃ (aluminum chloride) dissociates into 4 ions (Al³⁺ and 3Cl⁻) per formula unit. Number of ions = 4 ions/mol
Therefore, AlCl₃ would produce the greatest concentration of ions when 1.00 mol of each compound is dissolved in enough water to yield a 10.0 L solution.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
