Concentration of the ionic reactions:

Concentration of the ionic reactions:. Dissociation equations: Ex: NaCl (aq) → Na + (aq) + Cl - (aq) If the concentration of NaCl is 4.0 molar then each of the ions have the same concentration. NaCl (aq) → Na + (aq) + Cl - (aq) 4.0 M 4.0 M 4.0 M.

Presentation Transcript

  1. Concentration of the ionic reactions:

  2. Dissociation equations: • Ex: NaCl (aq) → Na+ (aq) + Cl- (aq) • If the concentration of NaCl is 4.0 molar then each of the ions have the same concentration. • NaCl (aq) → Na+ (aq) + Cl- (aq) • 4.0 M 4.0 M 4.0 M

  3. Ex: Dissociate MgCl2: MgCl2 (aq) → Mg2+ (aq) + 2Cl- (aq) • If the concentration of MgCl2 is 2.3 molar then: • MgCl2 (aq) → Mg2+ (aq) + 2Cl- (aq) • 2.3 M 2.3 M 2(2.3 M) • 4.6 M • Chlorine has twice as many ions therefore the concentration of the ions is double.

  4. Al2(SO4)3 (aq) → 2Al3+ (aq) + 3 SO42-(aq) • 3.6 M 7.2 M 10.8 M
