The Total solution for NCERT class 6-12
How are the colloidal solutionsclassified on the basis of physical states of the dispersed phase anddispersion medium?
One criterion for classifyingcolloids is the physical state of the dispersed phase and dispersion medium.Depending upon the type of the dispersed phase and dispersion medium (solid,liquid, or gas), there can be eight types of colloidal systems.
