BaCO3(s)<—>Ba²+ (aq) + CO3^-2(aq)
Ksp = 8.1 x 10^-9
The dissolution of BaCO3 (s) in water is represented above. A 20.0 mL sample of 1.0 x 10^-4 M Ba(NO3)2 (aq) is mixed with an 80.0 mL sample of 1.0 x 10^-4 M Na2CO₂ (aq). Which of
the following correctly predicts and explains the outcome?

a. A precipitate will form, because Q=1.0 x 10^-8
b. A precipitate will form, because Q=1.6 x 10^-9
c. A precipitate will not form, because Q=1.0 x 10^-8
d. A precipitate will not form, because Q-1.6 x 10^-9
