. The size of colloidal particles ranges between
A:10-7 – 10-9cm
B: 10-9 – 10-11cm
C: 10-5 – 10-7cm
D: 10-2 – 10-3cm
- A colloid is a combination in which one of the ingredients is broken down into extremely small particles and scattered throughout another.
- A dispersed phase is the material that is scattered, whereas a dispersion medium is the medium in which the initial substance is disseminated.
- Colloid particles typically range in size from 1 to 1000 nanometres.
- i.e. 10-5 to 10-7cm
- 10 – 5 – 10 – 7cm
Hence, the correct option is (c) 10-5 – 10-7cm
