Coagulating Value of Cl- Ion
Definition:
Coagulating value is the minimum concentration of an electrolyte required to precipitate a negative sol in one hour.
Given:
- 100 ml of 0.0018% (w/v) solution of Cl- ion was the minimum concentration of Cl- required to precipitate a negative sol in one hour.
To find:
- The coagulating value of Cl- ion.
Solution:
Step 1: Calculate the amount of Cl- ion present in the given solution.
- 0.0018% (w/v) means 0.0018 g of Cl- ion is present in 100 ml of solution.
- The molar mass of Cl- ion is 35.5 g/mol.
- Therefore, the number of moles of Cl- ion present in the solution is (0.0018/35.5) mol.
- The concentration of Cl- ion in the solution is (0.0018/35.5) x 1000 = 0.0507 mM.
Step 2: Calculate the coagulating value of Cl- ion.
- As per the definition, the coagulating value is the minimum concentration of an electrolyte required to precipitate a negative sol in one hour.
- Here, the given concentration of Cl- ion (0.0507 mM) is the minimum concentration required to precipitate a negative sol in one hour.
- Therefore, the coagulating value of Cl- ion is 1 mM (nearest integer).
Answer:
The coagulating value of Cl- ion is 1.

Coagulating value is the minimum concentration of electrolyte in milimoles required to cause coagulation of 1 litre solution.
100 mL = 0.1 L
0.0018 g Cl- ion, Molar Mass = 35.5
= 0.5070 = 1
100 mL = 0.1 L
0.0018 g Cl- ion, Molar Mass = 35.5
= 0.5070 = 1
