8. The Ksp for lead iodide (Pbl22) is 1.4 x 10-8. Calculate the solubility of lead iodide in each of the following: a. water b. 0.10 M Pb(NO3)2 c. 0.010 M Nal

Classify each statement as true or false. Statement a. AgCl with a Ksp of 1.6E-10 has a higher molar solubility than Ag2CrO4 with a Ksp of 2.0E-12. b. The solubility of AgCI(s) in water is higher than its solubility in 0.10M NaCI(ag). The Ksp of AgCl is 1.6E-10. c. In a galvanic cell made by connecting a Zn/Zn2+ half cell to a Au/Au3+ half cell, the cations in the salt bridge flow into the Au half cell. Zn2+ + 2e- Zn E° = -0.76V Au3++ 3e- → Au E° = 1.498V d. Consider a three-bulb system. Given six gaseous atoms, putting two atoms in each bulb has a lower entropy than distributing all six atoms in the middle bulb. |le. For the reaction O2(g) → 02(1) the reaction is spontaneous at low temperatures. > > >
