Question

The mixture of starch and water will exhibit particle size:

• A. Above $1000nm$
• B. $1-100nm$
• C. Below $0.1nm$
• D. $0.1-1nm$

Answer 1

The correct option is B

$1-100nm$

Answer:

A mixture of starch in water is an example of a colloidal solution.

colloidal solution:

• Colloids are heterogeneous mixtures in which particles of an insoluble substance are suspended throughout another substance
• The size of particles is between $1-100nm$.

Conclusion:

So, Starch and water solution is an example of the colloid solution so its particle size will be between $1-100nm$

Therefore, the correct option is option B.
