For coagulation of 50 mL of a sol, 10 mL of 0.5M Cl- ion solution is required. What is the coagulating value of Cl− ion s

The coagulating value of an ion is defined as the millimoles of that ion required to coagulate 1 mL of a sol.

Given that 10 mL of 0.5M Cl- ion solution is required to coagulate 50 mL of a sol, we can calculate the coagulating value as follows:

1. First, calculate the total millimoles of Cl- ions in the 10 mL solution. This is done by multiplying the volume of the solution (in liters) by the molarity.

   So, millimoles of Cl- = 10 mL * 0.5 mol/L = 5 mmol

2. Next, divide the total millimoles of Cl- ions by the volume of the sol to get the coagulating value.

   So, coagulating value of Cl- = 5 mmol / 50 mL = 0.1 mmol/mL

Therefore, the coagulating value of Cl- ions is 0.1 mmol/mL.
