Which statement describes coagulation value?a)Maximum amount (in milli...
The correct answer is option D: the coagulation value is the minimum amount (in millimoles) of electrolyte required to cause complete coagulation in one liter of colloidal solution.
Coagulation refers to the process of clumping together or aggregation of colloidal particles to form larger particles, which eventually settle down. This process is influenced by the presence of electrolytes in the solution. When the concentration of electrolytes exceeds a certain value, it leads to the destabilization of the colloidal particles and their subsequent coagulation.
To determine the coagulation value, we need to find the minimum amount of electrolyte required to cause complete coagulation in a given volume of colloidal solution. This value is usually expressed in terms of millimoles (mmol) of electrolyte per liter (L) of solution.
Explanation:
1. Coagulation: Explain the process of coagulation and its significance in colloidal systems.
- Coagulation is the process of clumping together or aggregation of colloidal particles, resulting in their precipitation or settling down. It is an important phenomenon in colloidal systems as it affects their stability and behavior.
- Coagulation can be induced by various factors, including the addition of electrolytes, change in pH, and temperature.
2. Coagulation Value: Define the coagulation value and its significance.
- The coagulation value represents the minimum concentration of electrolytes required to cause complete coagulation in a given volume of colloidal solution.
- It serves as a measure of the stability of the colloidal system. Lower coagulation values indicate a higher stability of the colloidal solution, as it requires a smaller amount of electrolyte to induce coagulation.
3. Measurement: Explain how the coagulation value is measured and expressed.
- The coagulation value is typically expressed in terms of millimoles (mmol) of electrolyte per liter (L) of colloidal solution.
- To determine the coagulation value, a series of experiments are conducted where varying concentrations of the electrolyte are added to the colloidal solution.
- The minimum concentration of electrolyte that results in complete coagulation is then identified as the coagulation value.
4. Significance: Discuss the significance of the coagulation value in practical applications.
- The coagulation value helps in understanding the stability and behavior of colloidal systems.
- It is particularly important in industries such as wastewater treatment, where coagulation is used as a method to remove colloidal particles and impurities from water.
- By knowing the coagulation value, appropriate amounts of electrolytes can be added to achieve efficient coagulation and purification of water.
In conclusion, the coagulation value represents the minimum amount (in millimoles) of electrolyte required to cause complete coagulation in one liter of colloidal solution. It is a measure of the stability of the colloidal system and plays a significant role in various practical applications, including water treatment.

Which statement describes coagulation value?a)Maximum amount (in milli...
The correct answer is option D
The coagulation of a colloidal solution by an electrolyte does not take place until the added electrolyte has certain minimum concentration in the solution. The minimum concentration of an electrolyte in millimoles per litre required to cause precipitation of a sol in two hours is called coagulating value. The smaller the quantity needed, the higher will be the coagulating power of an ion.
