I can answer flocculation value .I hope dono same hi hogi . my ans is 25 for flocclation and I heard that flocclation is inversely proposal to coagulation power to sayad 1/25 bhi aa sakta he par Jo bhi aye muje remind kar Dena.

Coagulation Value of CaCl2

Introduction
Coagulation is the process in which colloidal particles aggregate and form larger particles that settle down due to gravity. It is achieved by adding coagulants to the colloid. The coagulation value of a coagulant indicates the amount of that coagulant required to completely coagulate a given volume of colloid. In this case, we need to determine the coagulation value of CaCl2.

Given Information
- Volume of CaCl2 solution required for complete coagulation: 50 ml
- Concentration of CaCl2 solution: 0.1N
- Volume of colloid: 100 ml

Calculating Coagulation Value
The coagulation value can be calculated using the formula:

Coagulation Value = (Volume of Coagulant / Volume of Colloid) * Normality of Coagulant

Substituting the given values:

Coagulation Value = (50 ml / 100 ml) * 0.1N
Coagulation Value = 0.05 * 0.1N
Coagulation Value = 0.005N

Therefore, the coagulation value of CaCl2 is 0.005N.

Explanation
Coagulation is a process that involves the neutralization of charges on colloidal particles, causing them to come closer and form larger aggregates. The coagulant, in this case, CaCl2, provides ions that can neutralize the charge on the colloidal particles. As a result, the particles lose their stability and aggregate together.

To determine the coagulation value, we need to find the amount of CaCl2 required to neutralize the charges present in the colloid. The volume of CaCl2 solution required for complete coagulation is given as 50 ml. The concentration of the CaCl2 solution is 0.1N, indicating the number of moles of CaCl2 present in one liter of solution.

By using the coagulation value formula, we can calculate the coagulation value of CaCl2. The coagulation value is expressed in terms of normality (N), which represents the number of equivalents of a solute per liter of solution.

Substituting the given values into the formula, we find that the coagulation value of CaCl2 is 0.005N. This means that 0.005 moles of CaCl2 are required to completely coagulate 1 liter of the colloid.

Conclusion
The coagulation value of CaCl2 is 0.005N. This value represents the amount of CaCl2 required to fully coagulate a given volume of colloid. Coagulation occurs when the charges on colloidal particles are neutralized by the added coagulant, causing them to aggregate and settle down. The coagulation value helps in determining the appropriate dosage of coagulant for effective coagulation of colloidal systems.
