Question

The diameter of colloidal particle ranges from:

• A. ${10}^{-9}m$ to ${10}^{-6}m$
• B. ${10}^{-9}m$ to ${10}^{-12}m$
• C. ${10}^{3}m$ to ${10}^{-3}m$
• D. ${10}^{-3}m$ to ${10}^{-6}m$

Answer 1

The correct option is A ${10}^{-9}m$ to ${10}^{-6}m$

Size of colloidal particle ranges between 1 nanometer to 1 micrometer ${10}^{-6}-{10}^{-9}m$
