What are the properties of a colloid?
Properties of a colloid are:
1. The nature of colloidal solution is heterogeneous i.e. unlike. These solutions dwell in two different phases:
2. Despite the fact that colloidal dispersions are unlike in nature, yet the dispersed fragments are not detectable by human eye. This is due to the microscopic size of the particles in solution.
3. The size of the colloidal particles present in solution determines the colour of colloidal dispersion. Larger the size of the particles longer will be the wavelength of light being absorbed.
4. As a result of size, the colloidal fragments can easily be passed through a traditional filter paper. However these particles can be filtered by using membranes such as animal, cellophane and ultra filters.
