The coagulation values in millimoles per litre of the electrolytes used for coagulation of A{s}_{2}{S}_{2}aregivenbelow.<br/><br/>I.are given below.<br/><br/>I.NaCl = 52<br/><br/>II.<br/><br/>II.BaC{l}_{2} = 0.69<br/><br/>III.<br/><br/>III.MgS{O}_{4} = 0.22<br/><br/>Thecorrectorderoftheircoagulationis:<br/><br/>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 ∝1coagulatingpower∝ \dfrac{1}{coagulatingpower}

∴∴ Coagulating power A{s}_{2}{S}_{3}is<br/><br/>is <br/><br/>MgS{O}_{4} > BaC{l}_{2} > NaCl<br/><br/>III>II>I<br/><br/>III > II > I
