Question

In the rigorous classification of complex colloidal systems based completely on phase physical states, what exactly constitutes the 'dispersed phase' and 'dispersion medium' respectively in a standard metallurgical 'Foam'?

Prashant Kotian · Accepted Answer

Correct answer: B. A true Foam (such as the massive froth strictly utilized in the metallurgical froth flotation process) is scientifically classified as a colloidal dispersion where a Gas (the air bubbles) acts as the dispersed phase uniformly trapped within a continuous Liquid dispersion medium (the pine oil/water mixture).
