a Calculate the molar solubility of silver thiocyanate,
AgSCN, in pure water (
Ksp
1.0 × 10-¹2).
Solubility = 1.0x10^-6
=
A„By(s) ⇒ x A³+ (aq) + y B*− (aq)
Key = [A+] * [B²]
sp
The general equilibrium constant expression,
Ksp (solubility constant), for dissolving a poorly soluble salt
A By is:
Køp = [Ag+][SCN¯] = (x)(x) = x²
x = solubility of AgSCN in water
=
M
= 1.0 × 10-¹2
Correct
1.0 × 10-6 mol/L
M
b Calculate the molar solubility of silver thiocyanate, AgSCN (K = 1.0 × 10-¹2), in water containing 0.017 M NaSCN.
