The coagulation values in millimoles per litre of the electrolytes used for coagulation of A s 2 S 2 are given below. I. N a C l = 52 II. B a C l 2 = 0.69 III. M g S O 4 = 0.22 The correct order of their coagulation is:

Options

  1. AIII > I > II
  2. BI > II > III
  3. CII > I > III
  4. DIII > II > I

Correct answer

D. III > II > I

Step-by-step solution

Coagulation value ∝ 1 c o a g u l a t i n g p o w e r ∴ Coagulating power A s 2 S 3 is M g S O 4 > B a C l 2 > N a C l III > II > I
