Question

What size of particles does a colloidal system has?

• A. ${10}^{-4}mto{10}^{-10}m$
• B. ${10}^{-5}mto{10}^{-7}m$
• C. ${10}^{-9}mto{10}^{-12}m$
• D. ${10}^{-6}mto{10}^{-9}m$

Answer 1

The correct option is D ${10}^{-6}mto{10}^{-9}m$

The size of colloidal particle is in the range of ${10}^{-6}mto{10}^{-9}m$. Hence, (d) is the correct option.
