Question 1

The correct mathematical expression for finding the molar solubility (s) of Sn(OH)2 is:

2s2 = Ksp

2s3 = Ksp

108s5 = Ksp

4s3 = Ksp

8s3 = Ksp


Question 2

The following questions refer to the following system: 500.0 mL of 0.020 M Mn(NO3)2are mixed with 1.0 L of 1.0 M Na2C2O4. The oxalate ion, C2O4, acts as a ligand to form a complex ion with the Mn2+ion with a coordination number of two.

 

What is the equilibrium constant for the following formation?

Mn2++ 2C2O42–

[Mn(C2O4)2]2–

 
Mn2+ + C2O42– MnC2O4
 
K1 = 7.9 × 103
 
[Mn(C2O4)2]2– MnC2O4 + C2O42–
 
K2 = 1.26 × 10–2
 
Reference: Ref 16-2


1.0
3.7 × 102
2.1 × 10–1
6.3 × 105
None of these are correct.
