The correct Answer is:
To determine which lyophilic sol has the maximum protective power based on the given gold numbers, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Gold Number**: The gold number is a measure of the protective power of a colloid. It indicates the amount of the protective colloid required to prevent the coagulation of a certain amount of gold sol. A lower gold number signifies higher protective power. 2. **List the Gold Numbers**: From the question, we have the following gold numbers for the given lyophilic sols: - Casein: 0.01 - Haemoglobin: 0.03 - Gum Arabic: 0.15 - Sodium Oleate: 0.40 3. **Identify the Minimum Gold Number**: To find the sol with the maximum protective power, we need to identify the sol with the minimum gold number: - Casein: 0.01 (minimum) - Haemoglobin: 0.03 - Gum Arabic: 0.15 - Sodium Oleate: 0.40 4. **Conclusion**: Since Casein has the lowest gold number (0.01), it has the maximum protective power among the given options. ### Final Answer: The lyophilic sol with the maximum protective power is **Casein**. ---

the protective power of the lyophilic colloids es expressed in terms of gold number, a term introduced by Zsigmondy. Gold number is the number of milli - gram of the protective colloid which prevent the coagulation of 10 mLof red gold sol , when 1 mL of a 10 per cent solution of sodium chloride is added to it . thus smaller the gold number of lyophillic colloid, the greater is the protective power. On addition of one mL of sloution of 10 % NaCl to 10 mL. of red gold sol in presence of 0.025 g of starch the coagultion is just prevented . the gold number of starch is
