[SOLVED] Calculate the molar solubility of lead thiocyanate in 0.600M KSCN?

Calculate the molar solubility of lead thiocyanate in 0.600M KSCN?

Ksp for Pb(SCN)2 is 2.00*10^-5

Answer:

This is the Best answer for Calculate the molar solubility of lead thiocyanate in 0.600M KSCN?

Pb(SCN)2 <==> Pb^2+ + 2 (SCN)^-

. . s . . . . . . . . . .. . s . . . . . . 2s

KSCN ————-> K+ + SCN-

0.600 . . . . . . . . . . . . . . . 0.600

Ksp = [Pb^2+][CN^-]^2

2.00 10^-5 = (s)(2s+0.600)^2

s = 5.55 10^-5

the molar solubility of lead thiocyanate in 0.600M KSCN = 5.55 10^-5 mol/L

5.6*10^-5 is correct for mastering
