Garam yang paling mudah dalan larutan air A.ag2s(ksp=10-49) B.agl(ksp=10-16) C.Ag2crO4(ksp=10-2) D. AgCl(ksp=10-10)

Kelarutan

A. Ag2S ( Ksp = 10^-49 )
Ksp = [Ag+] [S2-]²
10^-49 = s ( 2s )²
10^-49 = 4s³
s = ³√ ( Ksp / 4 )
s = ³√ ( 10^-49 / 4 )
s = 3 × 10^-17

B. AgI ( Ksp = 10^-16 )
Ksp = s²
s = √Ksp
s = √ 10^-16
s = 10^-8

C. Ag2CrO4 ( Ksp = 10^-12 )
Ksp = 4s³
s = ³√ ( Ksp / 4 )
s = ³√ ( 10^-12 / 4 )
s = 6,3 × 10^-5

D. AgCl ( Ksp = 10^-10 )
Ksp = s²
s = √Ksp
s = √ 10^-10
s = 10^-5

Paling mudah larut ==> s paling besar => Ag2CrO4
