Coagulating value is inversely proportional to the coagulating power of an electrolyte
Definition: The coagulating value is defined as the amount of electrolyte (in millimoles) required to coagulate 1L of colloidal solution in 2 hours.
Moles = M × V = 0.5 × 20 mL = 10 mmol
Coagulating Value = 10 200 × 1000 = 50
The coagulating value is 50.
What is the molarity of a solution prepared by dissolving 5.85 g of NaCl in 500 mL of water?
(Molar mass of NaCl = 58.5 g/mol)
