Presentation Transcript

  1. 1. Consider the titration of 50.0 mL of 0.0450M Ag+ with 0.0280M Br-. How many mL of Br- solution are needed to reach the equivalence point? 80 mL 2. What is the concentration of Br- and Ag+ at the equivalence point? The Ksp for AgBr(s) = 5x10-13. 7.1 x 10-7 M = [Br-] = [Ag+]

  2. Consider the titration of 50.0 mL of 0.0450M Ag+ with 0.0280M Br-. The Ksp for AgBr = 5.0x10-13. 3. What is the concentration of Ag+ in solution after 100.0 mL of Br- solution have been added? [Ag+] = 1.4 x 10-10 M 4. What is the concentration of Ag+ in solution after 40.00 mL of Br- solution have been added? [Ag+] = 1.3 x 10-2 M
