Question

For the coagulation of 200 mL of As2S3 solution, 10 mL of 1 M NaCl is required. What is the coagulating value (number of milli moles of solute needed for coagulation of 1 liter of solution) of NaCl.

Accepted Answer

10 ml of 1 M NaCl contains NaCl = 10 &#215; 1 = 10 milli mole200 ml of As2S3 required NaCl for the coagulation = 10 milli mole&#8756; 1000 ml of As2S3 required NaCl for the coagulation = 10 &#215; 1000/200 = 50 milli mole
