Question
1. The Ksp is important because it can be used to calculate the concentrations of the ions in a saturated solution. For a solution of silver (I) chloride
A. Write the expression for Ksp for the salt.
B. If the Ksp of AgCl is 1.59 x 10-10 what is the concentration of silver in solution at saturation?
2. What is the molecular mass of KHT? (K C4O6 H5)?
3. For a solution of PbCl2 the Ksp is 1.2 x 10-5
A. Write the expression for Ksp for the salt.
B. If the Ksp of AgCl is 1.59 x 10-10 what is the concentration of silver in solution at saturation?
Please answer the questions with clearly written final answer
Explanation / Answer
1)
A)
AgCl (s) --------------> Ag+ (aq) + Cl- (aq)
expression :
Ksp = [Ag+][Cl-]
B)
Ksp of AgCl = 1.59 x 10^-10
Ksp = [Ag+][Cl-]
1.59 x 10^-10 = S^2
S = 1.26 x 10^-5 M
concentration of Ag+ = 1.26 x 10^-5 M
