Question

Define the following term
(a) Peptization
(b) Reversible sols​

Answer 1

Explanation:

Peptization-Peptization or Deflocculation is the process responsible for the formation of converting precipitate into colloid by shaking with it an electrolyte. ... When colloidal particles bear a same sign electric charge, they mutually repel each other and cannot aggregate together

Reversible sols-Reversible sols are such that if two constituents of the sol are separated by any means (such as evaporation), then the sol can be prepared again by simply mixing the dispersion medium with the dispersion phase and shaking the mixture.
