Dalam 1 liter larutan terdapat campuran garam BaCl2, SrCl2, CaCl2, yg masing masing konsentrasinya 0,02M jika ditambahkan 71 mg Na2SO4 Garam yang mengendap adalah.........
(Mr Na2SO4=142 ksp CaSO4 = 2 x 10^-5 SrSO4 = 2 x 10^-7 dan BaSO4 = 1 x 10^-10)
a CaSO4 dan SrSO4
b SrSO4
c BaSO4
d CaSO4
e SrSO4 dan BaSO4
bantu pakai caranya yaaa
