For the coagulation of 100ml of arsenious sulphide solution, 5ml of IM NaCl is required. Calculate the flocculation value. |
|
Answer» Solution :NUMBER of millimoles of electrolyte NaCl REQUIRED to coagulate 100ml of sol =1xx5=5. Number of millimoles of electrolyte required to coaguate 1000ml of sol =5xx10=50. The minimum number of moles of electrolyster PER litre required to cause precipitation is called floculation VALUE. Flocculating value of NaC=50millimole `L^(-1)` = 005 mol `L^(-1)` |
