Question

The size of particles in colloidal solution is:-
1.)Bigger then 10 raise to the power -5
2.)Smaller than 10 raise to the power -8
3.)Between 1 and 2nd option
4.)None of the above​​

Answer 1

A colloid is typically a two phase system consisting of a continuous phase (the dispersion medium) and dispersed phase (the particles or emulsion droplets). The particle size of the dispersed phase typically ranges from 1 nanometer to 1 micrometer
