Question

A sparingly soluble salt of the form MX (where M^+ is a metal cation and X is an anion) has a Ksp of 7.38 Times 10^-8. What is the expected concentration of M^+ ions if a sample of MX is placed in a litre of water? 7.38 Times 10^-8 mol/L 0.08 mol/L 2.72 Times 10^-4 mol/L 7.13 Times 10^-8 mol/L Measuring concentration of an ion potentiometrically requires: A capacitor A resistor A potential source A reference electrode In complex formation, a ligand with three donor groups iscalled: Bidentate Tridentate Amphiprotic Trichelate

Explanation / Answer

8)

MX ßà M +   +   X-

            s         s

Ksp = [M+][X-]

7.38*10^-8 = s^2

s = 2.72*10^-4 mol/L

[M+] = s = 2.72*10^-4 M
