Kelarutan garam berikut yang terkecil adalah... A.AgCl(Ksp = 1,6 x 10-10) B.AgCrO4(Ksp = 1,1 x 10-12) C.CaF2(Ksp = 4,0 x 10-11) D.Bi2S3(Ksp = 1 x 10-97) E.AuCl3

Jawaban

Kelarutan garam terkecil adalah Bi₂S₃ (Ksp = 1. 10⁻⁹⁷)

Penjelasan

AgCl

AgCl ---> Ag⁺ + Cl⁻

Ksp = s²

s = [tex]\sqrt{1,6~.10^{-10}}[/tex]

s = [tex]\sqrt{1,6}[/tex] . 10⁻⁵ M

AgCrO₄

AgCrO₄ ---> Ag⁺ + CrO₄⁻

Ksp = s²

s = [tex]\sqrt{1,1~.10^{-12}}[/tex]

s = [tex]\sqrt{1,1}[/tex] . 10⁻⁶ M

CaF₂

CaF₂ ---> Ca²⁺ + 2F⁻

Ksp = 4s³

s = [tex]\sqrt[3]{\frac{4}{4}~.10^{-11} }[/tex]

s = 1. [tex]10^{-5,5}[/tex] M

Bi₂S₃

Bi₂S₃  ---> 2Bi³⁺ + 3S²⁻

Ksp = 108s⁵

s = [tex]\sqrt[5]{\frac{1}{108}~.10^{-97} }[/tex]

s = [tex]\sqrt[5]{\frac{1}{108} }[/tex] [tex].10^{-19,4}[/tex] M

AuCl₃

AuCl₃ ---> Au³⁺ + 3Cl⁻

Ksp = 27s⁴

s = [tex]\sqrt[4]{\frac{3,2}{27}~.10^{-23} }[/tex]

s = [tex]\sqrt[4]{\frac{3,2}{27} }[/tex] [tex].10^{-5,75}[/tex] M
