A. Ksp BaCO₃ = 2,58 x 10⁻⁹ BaCO₃ <==> Ba²⁺ + CO₃²⁻ s s s Ksp = s² s² = Ksp = 25,8 x 10⁻¹⁰ s = 5,08 x 10⁻⁵ b. Ksp PbSO₄ = 2,52 x 10⁻⁸ PbSO₄ <==> Pb²⁺ + SO₄²⁻ s s s Ksp = s² s² = 2,52 x 10⁻⁸ s = 1,6 x 10⁻⁴ c. Ksp PbF₂ = 3,3 x 10⁻⁸ PbF₂ <==> Pb²⁺ + 2F⁻ s s 2s Ksp = s(2s)² = 4s³ 4s³ = 33,x,10⁻⁹ s³ = 8,25 x 10⁻⁹ s = 2 x 10⁻³ ------> Paling mudah larut d. Ksp SrCl₂ = 4,33 x 10⁻⁹ SrCl₂ <==> Sr²⁺ + 2Cl⁻ s s 2s Ksp = 4s³ 4s³ = 4,33 x 10⁻⁹ s³ = 1,0825 x 10⁻⁹ s = 1,027 x 10⁻³ 2. Soal kurang lengkap

yang b cuma ditulis Timbal Sulfat sama gurunya mas Dzaki
BaCO₃ <==> Ba²⁺ + CO₃²⁻
s s s
Ksp = s²
s² = Ksp
= 25,8 x 10⁻¹⁰
s = 5,08 x 10⁻⁵
b. Ksp PbSO₄ = 2,52 x 10⁻⁸
PbSO₄ <==> Pb²⁺ + SO₄²⁻
s s s
Ksp = s²
s² = 2,52 x 10⁻⁸
s = 1,6 x 10⁻⁴
c. Ksp PbF₂ = 3,3 x 10⁻⁸
PbF₂ <==> Pb²⁺ + 2F⁻
s s 2s
Ksp = s(2s)² = 4s³
4s³ = 33,x,10⁻⁹
s³ = 8,25 x 10⁻⁹
s = 2 x 10⁻³ ------> Paling mudah larut
d. Ksp SrCl₂ = 4,33 x 10⁻⁹
SrCl₂ <==> Sr²⁺ + 2Cl⁻
s s 2s
Ksp = 4s³
4s³ = 4,33 x 10⁻⁹
s³ = 1,0825 x 10⁻⁹
s = 1,027 x 10⁻³
