[SO₄⁻²] = 60 per 1000 dikali 0,2 = 0,012
BaCl₂ -> Ba²⁺ + 2Cl⁻
[Ba²⁺] = 40 per 1000 dikali 0,2 = 0,008
BaSO₄ -> Ba²⁺ + SO₄⁻²
Q = [Ba²⁺] [SO₄⁻²]
= (0,012) (0,008)
= 0,000096
= 9,6 * 10⁻⁵
jadi Q > Ksp maka terjadi endapan
[SO₄⁻²] = (60 /1000 ) . 0,2 = 0,012M
BaCl₂ -------> Ba²⁺ + 2Cl⁻
[Ba²⁺] = (40 /1000) . 0,2 = 0,008M
BaSO₄ -------> Ba²⁺ + SO₄⁻²
Q = [Ba²⁺] [SO₄⁻²]
= (0,012) (0,008)
= 0,000096
= 9,6 . 10⁻⁵
jadi Q > Ksp (terjadi endapan)
