Suppose you start with a solution that is at pH 8. If enough acid is added to make the [H+] 1000 times larger, what is the new pH? (Hint: Although this problem can be done using a calculator, it can easily be done in your head if you understand the principle.)   a. 3 b. 4 c. 7 d. 11 e. 5

The equilibrium 4 equation for the formation of the complex Cd(CN)42- is: Cd2+ + 4CN-    ⇌  Cd(CN)42- Write the equilibrium constant expression Kf , and then answer the following question. If Cd(CN)42- is a “typical” complex (which it is), which of the following statement(s) would you expect to be true? 1. At equilibrium, there will be more Cd2+ and CN- than Cd(CN)42- 2. At equilibrium, there will be more Cd(CN)42- than Cd2+ and CN- 3. The Kf value is small (- power of 10) 4. The Kf value is large (+ power of 10)   a. 2 and 4 only b. 1 and 3 only c. 1 and 4 only d. 2 and 3 only e. 2 only   Tables.pdf Periodic Table with New Elements.pdf
