Fill in the entire table and then answer the following questions.
please type the answers ( show all steps,
all these questions are related to that pre-lab table.
1. Fill in the following table with the Ksp values for any insoluble salt that forms from a metal ion in the left column and the anions in the other columns. Some have already been provided for you. If a salt is soluble in water write N/A.
|
a) Why were you unable to find some of the Ksp values for some ions?
|
|
2. In a test tube containing a precipitate of PbCrO4 in water: What are the concentrations of the lead (II) and chromate ions in equilibrium with the solid? Show your calculations. Use the Ksp from the Prelab table above .
[Pb+2] = M [CrO4-2] = M |
|
3. How can AgCl(s) be dissolved completely? |
|
(a) Write an equation for the reaction you described in (a). |
|
4. If HCl is added to a solution containing the following ions; Ag+, Mg2+, K+, and Ba2+, which ion(s) should precipitate based on your prelab Table? |
|
5. If sulfuric acid is added to a solution containing the following possible ions: Ag+, Ca2+, NH4+, and Pb2+, which ions should precipitate?
Type your response here. |
|
6. Notice 6M HCl is added to a solution containing all of the ions shown in Table 1. Answer the following:
|
|
a) Which ions will precipitate out of solution as metal chloride solids? |
|
b) Which of those metal chlorides is the most soluble in water? Hint: use Ksp values listed in your Prelab Table and calculate the molar solubility in water to prove your answer. |
