Problem- 1 what is the solubility of lead chloride pbcl2 in, Ask an Expert

Academics

Problem- 1) What is the solubility of lead chloride (PbCl2) in 0.505 M NaCl (aq)? The Ksp of PbCl2 = 2.4 x 10-4.

2) If 0.20 M NaOH was added dropwise to a solution containing 0.35 M Ca(NO3)2 and 0.50 M Fe(NO3)2, which would precipitate first, Ca(OH)2 or Fe(OH)2 ? The Ksp of Ca(OH)2 = 8 x 10-6 and the Ksp of Fe(OH)2 = 1.6 x 10-14. Justify your answer by giving the maximum hydroxide concentration for both Ca2+ and Fe2+ before precipitation would begin. Be sure to show your work.

Illustrate all work utilize additional paper if required.
