The correct Answer is:
To solve the question regarding the ability of an anion to bring about coagulation of a given colloid, we need to analyze the factors that influence this process. Here’s a step-by-step breakdown: ### Step 1: Understanding Coagulation Coagulation is the process where colloidal particles aggregate to form a larger mass or precipitate. This process is essential in various applications, including water purification and food processing. **Hint:** Coagulation involves the aggregation of particles in a colloid. ### Step 2: Role of Anions Anions are negatively charged ions. When introduced into a colloidal system, they can interact with the positively charged colloidal particles. The effectiveness of an anion in causing coagulation depends on its properties. **Hint:** Anions can neutralize the charge of colloidal particles. ### Step 3: Magnitude of Charge The magnitude of charge refers to the strength of the charge on the anion. A higher magnitude means a stronger interaction with the colloidal particles, leading to more effective coagulation. According to the Hardy-Schulze rule, the greater the charge of the anion, the more effective it is in coagulating the colloid. **Hint:** Greater charge magnitude leads to more effective coagulation. ### Step 4: Nature of Charge The nature of charge (whether it is positive or negative) is also crucial. For coagulation to occur, the anion must have a charge that can neutralize the charge of the colloidal particles. If the charge of the anion is not compatible with the charge of the colloid, coagulation will not occur. **Hint:** The charge type must be opposite to that of the colloidal particles. ### Step 5: Conclusion Thus, the ability of an anion to bring about coagulation depends on both the magnitude of its charge and the nature of its charge. Therefore, the correct answer to the question is that it depends on both the magnitude and the charge of the anion. **Final Answer:** The ability of anion to bring about coagulation of a given colloid depends upon both the magnitude and the nature of the charge.

coagultion is the process by which the dispersed phase of a colloid is made to aggregate and thereby separtate from the continuous phase. The minimum concetration of an eletrolyte in milli-moles per litre of the electrolyte solution which required to cause the caogultion of colloidal sol is called coagution value . therefroe higher is the coagulatings power of effective ion, smaller will be the coagultion value of the electrolyte. the ability of an ion to bring about coagulation of a given colloid depends upon :
