Ksp = 1.8E-10 = (Ag^+)(I^-)
............AgI(s) ==> (Ag^+)(I^-)
I...........solid........0.....0
C...........solid........x.....x
E...........solid........x.....x
Substitute the E line into the Ksp expression and solve for x.
.......Ca3(PO4)2 ==> 3Ca^2+ + 2PO4^3-
Qsp = (Ca^2+)^3(PO4^3-)^2
Qsp = (10^-5)^3(10^-6)2 = ?
Then compare Qsp with Ksp. Ksp is not listed in the problem.
a) Silver iodide(s) is formed by the following reaction:
Ag (aq) + I (aq) --> AgI (s)
The Ksp for AgI = 1.8 x 10^-10
Describe, using the chemical reaction, the mathematical formula for
these ions. Assuming these ion concentrations are equal, what would the molarity be for each ion?
b) Ca3(PO4)2 (s) is a chemical found in bones. If the solution used to preserve these bones contains 10^-5 M Ca^2+ and 10^-6 M PO4(^3-) would the bones soften and dissolve over time? Explain your answer
