What is the concentration of each ion in a 0.525 mol/L solution of magnesium chloride? mg=? cl=?

Chemistry
1 answer:
Vladimir [108]3 years ago
3 0

Answer:

Mg⁺² = 0.525 mol/L

Cl⁻ = 1.05 mol/L

Explanation:

The formula for magnesium chloride is MgCl₂, and in a solution the following process takes place:

  • MgCl₂ → Mg⁺² + 2Cl⁻

By analyzing the stoichiometric coefficients, we can tell that <em>the concentration of Mg⁺² ions is the same as the concentration of MgCl₂</em>, while the <em>Cl⁻ concentration is twice that value</em>.

In other words:

  • Mg⁺² concentration = MgCl₂ concentration = 0.525 mol/L
  • Cl⁻concentration = 2 * MgCl₂ concentration = 1.05 mol/L
