Question:
What type of solutions is starch in water?
What type of solutions is starch in water?
Show Hint
Starch molecules are large and strongly attracted to water, so they disperse easily in it.
Updated On: Nov 12, 2026
- true solution
- suspension
- lyophilic sol
- lyophobic sol

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
A colloid has particles of size 1 to 1000 nm. If the dispersed phase is strongly attracted to the solvent, the sol is called lyophilic (solvent loving).
Step 2: Apply to starch
Starch is a macromolecule, so its particles already lie in the colloidal range and it is not a true solution or a suspension.
It is strongly hydrated and disperses on simply warming with water, and the sol is stable and reversible.
Step 3: Conclusion
Such a solvent loving colloid in water is a hydrophilic or lyophilic sol.
Final Answer:
Starch in water forms a lyophilic sol. \[ \boxed{\text{(C) }\text{lyophilic sol}} \]
