ksp perak klorida AgCl : 3,6.10^-11 mol ^2L2. hitung kelarutan AgCl

Kelarutan & Hasil Kali Kelarutan
Kimia XI

Misalkan kelarutan = s (mol/liter)

AgCl ⇄ Ag⁺ + Cl⁻
   s         s        s

Ksp AgCl = [Ag⁺] [Cl⁻]
                = [ s ] [ s ]
                = s²

s = √ Ksp

s = √ [3,6 x 10⁻¹¹]

s = √ [36 x 10⁻¹²]

Jadi kelarutan AgCl sebesar 6 x 10⁻⁶ mol/liter
