Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Sols can carry positive or negative charge. Positively charged sols include hydrated metal oxides and basic dyes.
Step 2: Check Each Option
Starch, gum and gelatin form negatively charged sols.
Methylene blue is a basic dye and forms a positively charged sol.
Step 3: Compare the options
Methylene blue is option (C).
Final Answer:
Methylene blue forms a positively charged sol. \[ \boxed{\text{(C) }\text{Methylene Blue}} \]
