We’re being asked to calculate the molarity (M) of Ba2+ and Cl– in 0.15 M BaCl2 solution. Recall that:
• Dissociation of BaCl2: BaCl2(s) → Ba2+(aq) + 2 Cl–(aq)
A 0.15 M solution of BaCl2 contains:
A) 0.15 M Ba2+ ions and 0.15 M Cl- ions.
B) 0.15 M Ba2+ ions and 0.30 M Cl- ions.
C) 0.30 M Ba2+ ions and 0.15 M Cl- ions.
D) 0.30 M Ba2+ ions and 0.30 M Ci-ions.
E) none of the above
