200.0 mL of 0.005 M Na2CO3 are added to 200.0 mL of 0.002 M MgCl2. Does a precipitate form?
[Ksp(MgCO3) = 6.82 × 10–6]
Question 2 options:
|
|
No, because Q = Ksp. |
|
|
Yes, because Q > Ksp. |
|
|
No, because Q < Ksp. |
|
|
No, because Q > Ksp. |
|
|
Yes, because Q < Ksp. |
3.In order for a precipitate of PbBr2 to form, what is the minimum concentration of Br- that must be present in a solution of 0.00050 M Pb(NO3)2. The Ksp of PbBr2 is 2.20 × 10–6.
