The size of colloidal particles ranges between

A

10−7−10−9 cm10 ^ { - 7 } - 10 ^ { - 9 } \mathrm {~cm}

B

10−9−10−11 cm10 ^ { - 9 } - 10 ^ { - 11 } \mathrm {~cm}

C

10−5−10−7 cm10 ^ { - 5 } - 10 ^ { - 7 } \mathrm {~cm}

D

10−2−10−3 cm10 ^ { - 2 } - 10 ^ { - 3 } \mathrm {~cm}

Answer

10−5−10−7 cm10 ^ { - 5 } - 10 ^ { - 7 } \mathrm {~cm}

Explanation

Solution

The size of colloidal particles is 10−510 ^ { - 5 }to 10−710 ^ { - 7 } cm which is intermediate between true solutions and suspension.
