Question

characteristic of multimolecular solid lyophobic sols and emulsions

Answer 1

Answer:

(i) Multimolecular colloids (ii) Lyophobic sols (iii) Emulsions. 1. They are formed by the aggregate of a large number of atoms or molecules which generally have diameters less than 1 nm, e.g., sols of gold, sulphur etc. ... In an emulsion, one liquid (the dispersed phase) is dispersed in the other (the continuous phase).

Answer 2

Answer:

1. They are formed by the aggregate of a large number of atoms or molecules which generally have diameters less than 1 nm, e.g., sols of gold, sulphur etc.

2. Lyophobic sols: These sols are usually formed by the inorganic materials like metals, their sulphides etc.They are irreversible in nature i.e. once precipitated cannot return the colloidal sol by simply addition of the dispersion medium.
