2. Calcium Benzoate (CaBz2): a. A saturated CaBz2 sample solution is at equilibrium and the initially ion concentrations are [Ca+]ia and [Bz]i=b, CaBz₂(s)⇒Ca²+ (aq) +2Bz´¯(aq). This sample is allowed to saturate, and the remaining solids will be filtered out. The final benzoate ion concentration in solution is [BZ];= c as determined from titration. What is the solubility product of CaBz2 in terms of a, b and c? b. The lab experiment uses the saturated CaBz2 solution at equilibrium before titration. Why must the CaBz2 solution be saturated?

![2. Calcium Benzoate (CaBz2):
a.
A saturated CaBz2 sample solution is at equilibrium and the initially ion concentrations are
[Ca²+]ia and [Bz];=b,
CaBz₂(s)
Ca²+ (aq) + 2Bz¯(aq).
This sample is allowed to saturate, and the remaining solids will be filtered out. The final
benzoate ion concentration in solution is [BZ];= c as determined from titration. What is the
solubility product of CaBz2 in terms of a, b and c?
b. The lab experiment uses the saturated CaBz2 solution at equilibrium before titration. Why
must the CaBz2 solution be saturated?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7381ba0a-1476-4733-9910-c47c78f1b591%2Fbd480efe-1ac6-4f5a-97fb-368b3a6b2e8f%2Frg0tzb_processed.jpeg&w=3840&q=75)
