Given below are two statements:
Statement I:
In the coagulation of a negative sol, the flocculating power of the three given ions is in the order- Al³⁺ > Ba²⁺ > Na⁺
Statement II:
In the coagulation of a positive sol, the flocculating power of the three given salts is in the order NaCl > Na₂SO₄ > Na₃PO₄
In the light of the above statements, choose the most appropriate answer from the options given below:
