Kelarutan timbal II sulfat didalam air pada 298 k 1,2X10-4 mol dm -3 tinbal II sulfat didalam satu liter H2SO4 1M adalah

s = 1,2 × 10^-4 mol/L

Ksp = [Pb2+] [SO4^2-]
Ksp = s ( 2s )²
Ksp = 4s³ = 4 ( 1,2 × 10^-4 )³ = 4,8 × 10^-12

Dalam H2SO4 1 M
Ksp = [Pb2+] [SO4^2-]
Ksp = s ( 1 M )
s = Ksp = 4,8 × 10^-12 mol/L
